Then ask the user to enter current date. Display the names of those employees whose service is 15 or more than 15 years according to the given current date.
Answer:
The program in C is as follows:
#include<stdio.h>
#include<conio.h>
struct employee{
char empname[50]; int empcode, day,mon,yr;
}employees[30];
int main(){
int total;
printf("Numbers of Employees : "); scanf("%d",&total);
for(int kt=0;kt<total;kt++){
printf("Employee Code : "); scanf("%d",&employees[kt].empcode);
printf("Name: "); scanf("%s",employees[kt].empname);
printf("Date of Joining [dd mm yyyy]: "); scanf("%d%d%d",&employees[kt].day,&employees[kt].mon,&employees[kt].yr); }
int year;
printf("\nCurrent Date [Year only]: "); scanf("%d", &year);
printf("Code\t\t\t Name\t\t\t Date of Joining\n");

Consider the method get Hours, which is intended to calculate the number of hours that a vehicle takes to travel between two mile markers on a highway if the vehicle travels at a constant speed of 60 miles per hour. A mile marker is a sign showing the number of miles along a road between some fixed location (for example, the beginning of a highway) and the current location. IN The following table shows two examples of the intended behavior of getHours, based on the int parameters markeri and marker2. marker1 marke 100 220 100 700.5 Consider the following implementation of getHours. public static double getHours (int markeri, int ON 20 | 2 15. . . e no E /* missing statement */ return hours; Which of the following statements can replace /* missing statement */ so getHours works as intended?
(A) double hours = (Math.abs (markerl) - Math.abs (marker2)) / 60.0;||
(B) double hours = Math.abs (markeri - marker2 / 60.0)
(C) double hours = Math.abs (marker1 - marker2) / 60.0;
(D) double hours = Math.abs((markeri - marker2) / 60);
(E) double hours = (double) (Math.abs (marker1 - marker2) / 60);
Answer:
Replace the comment with:
(c) double hours = Math.abs (marker1 - marker2) / 60.0;
Explanation:
See attachment for right presentation of question
Analyzing the options:
(a): May return a negative result
This option will return a negative value if marker1 is less than marker2 because it subtracts the absolute value of marker2 from the absolute value marker1.
This literally is not different from marker1 - marker2
(b): Incorrect expression
This divides only marker2 by 60, then subtracts the quotient from marker1. This is not the expected expression.
(c) This option is correct
This correctly calculate the positive difference between marker1 and marker2 and the result is divided by 60.0 (note 60.0 not 60)
(d) & (e) Integer division
When a variable declared as double is divided by an integer variable or value, the result of the computation is not always accurate due to approximation
what are the main technologies that have contributed to the growth and commercialization of the internet .
Answer:
Explanation: The main forces that led to the commercialization of the internet are its demand and the importance of the Internet.
TCP and IP technologies allowed for the connection of many networks to form on large network. This tech used packets and provided error-recovery mechanisms. Hence many small networks were combined to form the internet.
There are several technology of the Internet and the World Wide Web. The hand of projects in computer networking, mostly funded by the federal government.
The projects made communications protocols that shows the format of network messages, prototype networks, and application programs such as browsers.The advent of computer devices and telephone network was the underlying physical infrastructure upon which the Internet was built. The commercialization and exponential growth of the internet started in the early 1990s.
It was due to high meetup of technologies, including the development of personal computers with graphical operating systems, widespread availability of internet connection services, the removal of the restriction of commercial use on NSFnet, etc.
Conclusively, These happenings combined to give the commercial push for an easy way to share and access information.

Subtraction + Decision and Loop
This is a twist on the previous exercise that will help you review loops and decision structures. You will again ask the user to enter two numbers. However, you will ALWAYS subtract the smaller number from the larger number to ensure that you never get a negative number for an answer. You do this by checking the numbers and switching them if they are not in the right order (larger then smaller). All of this checking, switching, subtracting, and output of the answer should occur in a function.
((( THIS WAS THE PREVIOUS EXERCISE
Function Basics - Arguments and Parameters
This is another easy exercise to test your knowledge of the fundamentals. In main(), ask the user to enter two integers. Pass those two integers to a function that will subtract one number from another. This function must also output the answer to the user.
Output:
Enter two integers (separated by a space) and this program will subtract them: [user enters: 5 7]
5 - 7 = -2
Notes and Hints:
1) From now on, you must use a function prototype for all programs that use functions. Don't expect me to ask for it in each exercise. )))
Finally, ask the user if they would like to run the program again. By now, you should know exactly what type of loop to use.
Output:
Enter two integers (separated by a space) and this program will subtract the smaller from the larger: [user enters: 7 5]
7 - 5 = 2
Do you want to run this program again? [user enters: y]
Enter two integers (separated by a space) and this program will subtract the smaller from the larger: [user enters: 5 7]
7 - 5 = 2
Do you want to run this program again? [user enters: n]
Notes and Hints:
1) As always, make sure you accept an upper or lower case 'Y'
Answer:
In Python:
def subsmall(num1,num2):
if num1 > num2:
return num1 - num2
else:
return num2 - num1
repeat = True
while(repeat):
num = input("Enter two integers: ")
nums = num.split(" ")
print(subsmall(int(nums[0]),int(nums[1])))
runagain = input("Run program again? ").lower()
if runagain == "y":
repeat=True
else:
repeat = False
Explanation:
The function begins here
def subsmall(num1,num2):
This subtracts num2 from num1 if num2 is smaller
if num1 > num2:
return num1 - num2
If otherwise, subtract num1 from num2
else:
return num2 - num1
The main begins here
This initialiazes a boolean variable to true
repeat = True
This loop is repeated until the boolean variable is false
while(repeat):
Prompt to enter two integers
num = input("Enter two integers: ")
Split the string by space
nums = num.split(" ")
This passes the two integers to the function and also prints the differences
print(subsmall(int(nums[0]),int(nums[1])))
Prompt to run the program again
runagain = input("Run program again? ").lower()
If input is Y or y, the loop repeats
if runagain == "y":
repeat=True
The program ends if otherwise
else:
repeat = False
Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly. Do not store in a variable.). Ex: If the input is: 200000 210000 the output is: This house is $200000. The change is $-10000 since last month. The estimated monthly mortgage is $850.0. Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.
Answer:
In Python:
cprice= int(input("Current price: "))
lmonth= int(input("Last month's price: "))
print("This house is $"+str(cprice))
print("The change is $"+str(cprice-lmonth)+" since last month")
print("The current mortage $"+str((cprice * 0.051) / 12)+" since last month")
Explanation:
Get current price
cprice= int(input("Current price: "))
Get last month's price
lmonth= int(input("Last month's price: "))
Print the current price
print("This house is $"+str(cprice))
Print the change
print("The change is $"+str(cprice-lmonth)+" since last month")
Print the mortgage
print("The current mortage $"+str((cprice * 0.051) / 12)+" since last month")

Explanation:
Imagine a room full of boxes. Each box has a length, width, and height. Since the boxes can be rotated those terms are inter- changeable. The dimensions are integral values in a consistent system of units. The boxes have rectangular surfaces and can be nested inside each other. A box can nest inside another box if all its dimensions are strictly less than the corresponding dimensions of the other. You may only nest a box such that the corresponding surfaces are parallel to each other. A box may not be nested along the diagonal. You cannot also put two or more boxes side by side inside another box.The list of boxes is given in a file called boxes.txt. The first line gives the number of boxes n. The next n lines gives a set of three integers separated by one or more spaces. These integers represent the 3 dimensions of a box. Since you can rotate the boxes, the order of the dimensions does not matter. It may be to your advantage to sort the dimensions in ascending order.boxes.txt contains:2023 90 70 48 99 56 79 89 91 74 70 91 91 53 56 22 56 39 64 62 29 92 85 15 23 61 78 96 51 52 95 67 49 93 98 25 57 94 82 95 93 46 38 50 32 50 89 27 60 66 60 66 43 37 62 27 14 90 40 16 The output of your code will be the largest subset of boxes that nest inside each other starting with the inner most box to the outer most box. There should be one line for each box.Largest Subset of Nesting Boxes(2, 2, 3)(3, 4, 4)(5, 5, 6)(6, 7, 9)If there is two or more subsets of equal lengths that qualify as being the largest subset, then print all the largest qualifying subsets with a one line space between each subset. The minimum number of boxes that qualify as nesting is 2. If there are no boxes that nest in another, then write "No Nesting Boxes" instead of "Largest Subset of Nesting Boxes".For the data set that has been given to you, here is the solution set:Largest Subset of Nesting Boxes[14, 27, 62][16, 40, 90][53, 56, 91][57, 82, 94][14, 27, 62][27, 50, 89][53, 56, 91][57, 82, 94][14, 27, 62][37, 43, 66][53, 56, 91][57, 82, 94][22, 39, 56][27, 50, 89][53, 56, 91][57, 82, 94][22, 39, 56][37, 43, 66][53, 56, 91][57, 82, 94][32, 38, 50][37, 43, 66][53, 56, 91][57, 82, 94]

Explanation:
Create a class called Jack that extends Leo. This class must have the following behaviors/methods. You must use the inheritance to reuse the methods from the parent classes. Solution without using the inheritance will get zero points. re-writting the code that already exists will get zero credit. A call to the methods in the parent classes must be donemethod description
method1 display "Jack 1 Leo 1 "
method2 displays "Don 2 Jack 2"
method3 displays "Jack 3 Leo 3 Don 2 "
toString displays" Jack 3 Leo 1"
Answer:
public class Leo{
public String method1(){
return "Jack 1 Leo 1";
}
public String method2(){
return "Don 2 Jack 2";
}
public String method3(){
return "Jack 3 Leo 3 Don 2";
}
public String toString(){
return "Jack 3 Leo 1"
}
}
public class Jack extends Leo{
}
Explanation:
Leo is the parent class and jack inherits all of its attributes from Leo
So when you call the following code in the main method:
Jack j = new Jack();
System.out.println(j.method1);
it should print Jack 1 Leo 1
This is because the program first checks if method 1 exists in the Jack class
Because it doesn't exist it then goes to the parent class which is Leo.
And in the Leo class method1 displays "Jack 1 Leo 1 "
So it prints that
function _one(array)
Create a JavaScript function that meets the following requirements:
•
•
•
•
Please give your function a descriptive name
o ( _one is not acceptable, and is only displayed here for illustration purposes)
Receives an array of integers as an argument
The function removes all duplicates (if they exist) from the array and returns it to the caller.
Assume the input array parameter will have at least one element in it.
Examples :
_one([33])
➔ [33]
_one([33, 33, 1, 4])
➔ [1, 4]
_one([33, 33, 1, 4, 1]) ➔ [4]
Answer:
function removeRepeaters(list){
var goodList = [], badList = {}, used = {}, n;
// ensure that the argument is indeed an array
if(!Array.isArray(list)){
throw "removeRepeaters: Expecting one argument of type Array";
}
// loop through the array and take note of any duplicates
for(n in list) used[list[n]] == true ? badList[list[n]] = true : used[list[n]] = true;
// now loop through again, and assemble a list of non-duplicates
for(n in list) if(badList[list[n]] == undefined) goodList[] = list[n];
return goodList;
}
Explanation:
I assume you're familiar with trinary operators, but just in case, that's what's happening in this first for loop:
for(n in list) used[list[n]] == true ? badList[list[n]] = true : used[list[n]] = true;
this is the same as saying:
for(n in list){
if(used[list[n]] == true){
badList[list[n]] = true;
} else {
used[list[n]] = true;
}
}
This loop flags all of the values in the list that are duplicated. Note that both "badList" and "used" are declared as objects instead of arrays. This allows us to compare keys in them with an == operator, even if they're not defined, making it a convenient way to flag things.
Note that I haven't tested it, so I may have overlooked something. I suggest testing it before handing it in.

Wesley purchased a word-processing software program. He used it for a year, during which he got regular updates every two months. After a year, he was not allowed to update the software. However, he could continue using it. Why did the updates stop?
Group of answer choices.
A. The software was corrupt and resulted in a bug.
B. He purchased a license with maintenance for a year.
C. The organization discontinued the software.
D. He purchased an open-source license.
E. He purchase a perpetual non-maintenance license.
Answer:
B. He purchased a license with maintenance for a year.
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.
Basically, softwares are categorized into two (2) main categories and these are;
I. Open-source software.
II. Proprietary software.
A proprietary software is also known as a closed-source software and it can be defined as any software application or program that has its source code copyrighted and as such cannot be used, modified or distributed without authorization from the software developer. Thus, it is typically published as a commercial software that may be sold, licensed or leased by the software developer (vendor) to the end users with terms and conditions.
In this scenario, Wesley purchased a word-processing software program. He used it for a year, during which he got regular updates every two months. However, after a year, he was not allowed to update the software but he could continue using it.
This ultimately implies that, Wesley purchased a licensed software with maintenance for a year and as such he would stop receiving an update from the software developer after his subscription expired.

#include <stdlib.h>
int main() {
int r,c;
printf("Row: "); scanf("%d", &r);
printf("Cols: "); scanf("%d", &c);
double *myarr = (int *)malloc(r * c * sizeof(int));
double inputs = 0.0;
for (int rww = 0; rww < r; rww++){
for (int ccl = 0; ccl < c; ccl++){
inputs= inputs+1.0;
*(myarr + rww*ccl + ccl) = inputs; }}
return 0;}
Explanation:
This declares the rows and columns as integers
int r,c;
This gets the number of rows
printf("Row: "); scanf("%d", &r);
This gets the number of columns
printf("Cols: "); scanf("%d", &c);
This dynamically allocate space for array myart
double *myarr = (int *)malloc(r * c * sizeof(int));
This initializes the inputs to the array to 0.0
double inputs = 0.0;
This iterates through the array and initializes each element of the array by its index
for (int rww = 0; rww < r; rww++){
for (int ccl = 0; ccl < c; ccl++){
inputs= inputs+1.0;
*(myarr + rww*ccl + ccl) = inputs; }}
