Question

b) #include <iostream>
using namespace std;
int main()
{
int x = 0, y = 2;
x = y * 4;
cout << x << endl << y << endl;
return 0;
}

Explanation:

Step1: Analyze variable initialization

We have int x = 0, y = 2;, so initially \( x = 0 \) and \( y = 2 \).

Step2: Analyze the assignment to x

The line x = y * 4; means we calculate \( y\times4 \). Substituting \( y = 2 \), we get \( x=2\times4 = 8 \). The value of \( y \) remains unchanged as we only assigned a new value to \( x \).

Step3: Analyze the output statement

The cout statement prints \( x \) first, then \( y \), each followed by a new line. So it will print the value of \( x \) (which is 8) and then the value of \( y \) (which is 2).

Answer:

The output of the program will be:
\( 8 \)
\( 2 \)
