write a 2d array c program that can capture marks of 15 students and display the maximum mark, the sum and average​

Answers

Answer 1

Answer:

#include <stdio.h>  

int MaxMark(int* arr, int size) {

   int maxMark = 0;

   if (size > 0) {

       maxMark = arr[0];

   }

   for (int i = 0; i < size; i++) {

       if (arr[i] > maxMark) {

           maxMark = arr[i];

       }

   }

   return maxMark;

}

int SumMarks(int* arr, int size) {

   int sum = 0;

   for (int i = 0; i < size; i++) {

       sum += arr[i];

   }

   return sum;

}

float AvgMark(int* arr, int size) {

   int sum = SumMarks(arr, size);

   return (float)sum / size;

}

int main()

{

   int student0[] = { 7, 5, 6, 9 };

   int student1[] = { 3, 7, 7 };

   int student2[] = { 2, 8, 6, 1, 6 };

   int* marks[] = { student0, student1, student2 };

   int nrMarks[] = { 4, 3, 5 };

   int nrStudents = sizeof(marks) / sizeof(marks[0]);

   for (int student = 0; student < nrStudents; student++) {              

       printf("Student %d: max=%d, sum=%d, avg=%.1f\n",  

           student,

           MaxMark(marks[student], nrMarks[student]),

           SumMarks(marks[student], nrMarks[student]),

           AvgMark(marks[student], nrMarks[student]));

   }

   return 0;

}

Explanation:

Here is an example using a jagged array. Extend it to 15 students yourself. One weak spot is counting the number of marks, you have to keep it in sync with the array size. This is always a problem in C and would better be solved with a more dynamic data structure.

If you need the marks to be float, you can change the types.

(TCOE) When a customer purchases software that displays a clickwrap agreement at the time of installation, the consumer has already purchased the product and is being asked to consent to the contract that purportedly memorializes the payment. Is the contract formed at the moment of purchase or later, when the buyer assents to the terms of the clickwrap agreement?

Answers

Answer:

The analysis is presented throughout the section described, as per the given situation.

Explanation:

Those requirements as well as agreements do not apply to something like the acquisition of the commodity. But perhaps the terms and agreements are all about the use of the name. This means that for illegal or immoral procedures, when and how to use the item and even the component shouldn't be used. The overall profitability certainly comes with either the commodity themselves as well as during implementation, trying to give one's authorization has always been about the service mostly with the supplier.

However, during implementation, the contract is something different from the place where you live throughout your purchase.

Write code to complete RaiseToPower(). Sample output if userBase is 4 and userExponent is 2 is shown below. Note: This example is for practicing recursion; a non-recursive function, or using the built-in function pow(), would be more common.
4^2 = 16
#include
int RaiseToPower(int baseVal, int exponentVal){
int resultVal = 0;
if (exponentVal == 0) {
resultVal = 1;
}
else {
resultVal = baseVal * /* Your solution goes here */;
}
return resultVal;
}
int main(void) {
int userBase = 0;
int userExponent = 0;
userBase = 4;
userExponent = 2;
printf("%d^%d = %d\n", userBase, userExponent, RaiseToPower(userBase, userExponent));
return 0;
}

Answers

Answer:

Replace /* Your solution goes here */ with

RaiseToPower(baseVal, exponentVal-1);

Explanation:

From the question, we understand that the program uses recursion.

The essence of recursion is to call a function from the function itself.

This is done by RaiseToPower(baseVal, exponentVal-1);

Because it passed the baseVal and the exponentVal reduced by 1 to the RaiseToPower function.

This is repeated until exponentVal = 1.

However, I've added the full program as an attachment where I used comments to explain some lines.

In this exercise we have to use the knowledge of computational language in C++ to write the code.

This code can be found in the attached image.

To make it simpler the code is described as:

#include<iostream>

#include<stdio.h>

int RaiseToPower(int baseVal, int exponentVal){

int resultVal = 0;

if (exponentVal == 0) {

resultVal = 1;

}

else {

resultVal = baseVal * RaiseToPower(baseVal, exponentVal-1);

}

return resultVal;

}

int main(void) {

int userBase = 0;

int userExponent = 0;

userBase = 4;

userExponent = 2;

printf("%d^%d = %d\n", userBase, userExponent, RaiseToPower(userBase, userExponent));

return 0;

Write a program that prompts the user to enter a date, using integer values for the month, day, and year, and then prints out the day of the week that fell on that date. According to the Gregorian Calendar, January 1, 1601 was a Monday. Observe all leap years (and keep in mind that 1700, 1800, and 1900 were not leap years).

Answers

Answer:

import datetime

user = input("Enter date in yyyy,m,d: ").split(",")

int_date = tuple([int(x) for x in user])

year, month, day =int_date

mydate = datetime.datetime(year, month, day)

print(mydate)

x = mydate.strftime("%B %d, %Y was a %A")

print(x)

Explanation:

The datetime python module is used to create date and time objects which makes it easy working with date-time values. The user input is converted to a tuple of integer items, then they are converted to date time objects and parsed to string with the strftime method.

Write a SELECT statement that returns these four columns:

vendor_name-The vendor_name column from the Vendors table
invoice_number The invoice_number column from the Invoices table
invoice_date The invoice date column from the Invoices table
balance due The invoice total column minus the payment total and credit total columns from the Invoices table

Use these aliases for the tables: v for Vendors and i for Invoices.

Return one row for each invoice with a non-zero balance.
This should return 11 rows. Sort the result set by vendor_name in ascending order

Answers

Answer:

SELECT vendor_name, invoice_number, invoice_date,

(invoice_total - payment_total - credit_total) AS balance_due

FROM vendors AS v JOIN invoices AS i

ON vendors.vendor_id = Invoices.vendor_id

WHERE invoice_total - payment_total - credit_total > 0

ORDER BY vendor_name;

Explanation:

The query statement returns joint records of vendor name, invoice number, invoice date, and balance due from the vendor and invoice tables represented with aliases v and i respectively.

It returns an output with the WHERE clause condition to only return balance due greater than zero and the output is returned in ascending order of the vendor's names.

The term Linux Intrusion Detection System ( LIDS) refers to a command that allows an administrator to run processes as root without actually logging in under the root account in a Linux or UNIX system. A. True B. False

Answers

Answer:

B. False

Explanation:

The term Super user do (sudo) refers to a command that allows an administrator to run processes as root without actually logging in under the root account in a Linux or UNIX system.

On the other hand, a Linux Intrusion Detection System can be defined as a patch to the operating system kernel of the Linux machine, as well as a set of administrative tools that is typically used to improve the security of the Linux kernel through the implementation of a mandatory access control known as MAC.

Hence, the Linux Intrusion Detection System can be used to deny any unauthorized use of the input or output device, memory, raw devices, file access and other network administrative functions.
