Answer:
II and III
Explanation:
(i) would only evaluate to true if all variables are equal.
(ii) evaluates to true if one or more of the clauses is true.
(iii) if two variables are equal, at least one factor will evaluate to 0, making the result of the multiplication zero and thus the expression true.
You are asked to write a program that will display a letter that corresponds with a numeric rating system. The program should use a switch statement. The numeric rating is stored in a variable named rate and rate may equal 1, 2, 3, or 4. The corresponding letter is stored in a variable named grade and grade may be A, B, C, or D. Which is the test expression for this switch statement
The switch statements are similar to the if statements in a computer program
The test expression for the switch statement is the variable rate
How to determine the test expressionFrom the question, we have the following highlights
The program displays a corresponding letter of a rateThe rating is stored in the variable rateThis means that, the numerical value of the variable rate would be tested and the corresponding letter would be printed
Hence, the test expression for the switch statement is the variable rate

A restaurant recorded the ages of customers on two separate days. You are going to write a program to compare the number of customers in their twenties (ages 20 to 29). What is the missing line of code to count the number of customers in their twenties? customerAges = [13, 3, 11, 24, 35, 25, 15, 18, 1] count20s = 0 if 20 <= item <= 29: count20s = count20s + 1
Answer:
You will need to implement a for loop ( I am assuming this is java)
Explanation:
int count20s = 0;
for(int x =0; x< customerAges.length;x++){
if(20 <= customerAges[x] && customerAges[x] <= 29){
count20s++;

This program reads a file called 'test.txt'. You are required to write two functions that build a wordlist out of all of the words found in the file and print all of the unique words found in the file. Remove punctuations using 'string.punctuation' and 'strip()' before adding words to the wordlist.
Write a function build_wordlist() that takes a 'file pointer' as an argument and reads the contents, builds the wordlist after removing punctuations, and then returns the wordlist. Another function find_unique() will take this wordlist as a parameter and return another wordlist comprising of all unique words found in the wordlist.
Example:
Contents of 'test.txt':
test file
another line in the test file
Output:
['another', 'file', 'in', 'line', 'test', 'the']
This the skeleton for 1:
#build_wordlist() function goes here
#find_unique() function goes here
def main():
infile = open("test.txt", 'r')
word_list = build_wordlist(infile)
new_wordlist = find_unique(word_list)
new_wordlist.sort()
print(new_wordlist)
main()
Answer:
Explanation:
The following code has the two requested functions, fully working and tested for bugs. It is written in Python as is the sample code in the question and a sample output can be seen in the picture attached below.
import string
def build_wordlist(file_pointer):
words = file_pointer.read()

Consider the following code segment.
int a = 0;
int b = 3;
while ((b != 0) && ((a / b) >= 0)
{
a = a + 2;
b = b - 1;
}
What are the values of a and b after the while loop completes its execution?
a = 4, b = 1
a = 0, b = 3
a = 6, b = 0
a = 8, b = -1
Answer:
a=4 , b=1
Explanation:
I'm not a computer science major at all but I think I can help you with this code.
Our program wants us to add 2 to a get new a value while also subtracting 1 from b value to obtain new b value. We we want to for for as long b is not 0 and a/b is nonnegative.
One round we get:
New a=0+2=2
New b=3-1=2
Let's see if we can go another round:
New a=2+2=4
New b=2-1=1
We can't go another round because b would be negative while a is positive which would make a/b negative. So our loop stops at this 2nd round.
a=4 , b=1
Other notes:
2nd choice makes no sense because a is always going to increase because of the addition on a and b was going to decrease because of the subtraction on it.
Third choice makes no sense because a/b doesn't even exist.
Fourth choice a/b is negative not nonnegative.

The memory hierarchy of a computer system organizes storage by using small, fast, expensive memories at the top of the hierarchy and supplementing them with larger, slower, cheaper memories at each successive level. Explain how the principle of memory locality makes such a system capable of providing efficient access to the data and instructions needed for executing programs.
Answer:
Following are the responses to this question:
Explanation:
The computer system's memory hierarchy arranges space through tiny, fast, costly stocks only at top of the pyramid and complements them through big, lighter, cheap storage facilities at every representation made. It is needed to limit the time for data access for application executes. A very design of the main memory allows a system to have easy access to the information and instructions necessary to execution time. A traditional technique of system memory works like:
[tex]Level\ 0 (Top Level) \to CPU \ Registers\\\\Level \ 1 \to Cache\ Memory \ (SRAMs)\\\\Level\ 2 \to Main \ Memory \ (DRAMs)\\\\Level \ 3 \to Magnetic \ Disk\ (Disk \ Storage)\\\\Level \ 4 \to Optical \ Disk\\\\Level \ 5 \to Magnetic\ Tape\\\\[/tex]
Because as memory cost rises below level 5 to level 0. CPU registers become costly as the cache memory, which then, in turn, is much more costly than for the memory.
Whenever the access time of CPU registries becomes reduced from level 5 to level 0, its time complexity between reading/write transactions is much more swift than Cache Memory Access period which in turn is quicker than that of the main memory Communication cost and so forth.
So, we need a memory hierarchy to analyze the information (read/write requests) efficiently, in turn for all the top-level to read the information more quickly and thoroughly. Therefore, the architecture of the computer program's Main memory enables a system to provide secure access to information and guidance for running programs.

function changeNums(numList, addNum, subtractNum) {
for(var i=0; i
if(numList[i] % 3 == 0){

} else {

}
}
}
changeNums (numbers, 3, 2);
console.log(numbers);
The output that will be printed to console after the program runs is (b) [0, 3, 6, -1, 9]
When the program is analyzed, we have the following highlights
The program increases numbers that are divisible by 3, by the value of variable addNumOther numbers are reduced by the value of variable subtractNumIn the program, the values of addNum and subtractNum are 3 and 2, respectively.
In the list, 3 and 6 are divisible by 3
2, 5 and 1 are not divisible by 3
When the program runs, 3 and 6 are replaced by 6 and 9.
While 2, 5 and 1 are replaced by 0, 3 and -1
Hence, the output that will be printed to console after the program runs is (b) [0, 3, 6, -1, 9]

return x;

return 8 * x;
return 3 + x;
return 3 * x;
return 6 * x;
return 4 * x;
Answer:
return 8 * x
Explanation:
Given
The attached code segment
Required
Which single statement can replace the program body
From calculate(), we have:
[tex]x = x + x;\\ x = x + x;\\ x = x + x;[/tex]
The first line (x = x + x) implies that:
[tex]x=2x[/tex]
So, on the next line; 2x will be substituted for x
i.e.
[tex]x = x + x[/tex] becomes
[tex]x = 2x + 2x[/tex]
[tex]x = 4x[/tex]
So, on the third line; 4x will be substituted for x
i.e.
[tex]x = x + x[/tex] becomes
[tex]x = 4x+ 4x[/tex]
[tex]x = 8x[/tex]
In programming: 8x = 8 * x:
This means that: return 8 * x can be used to replace the body
