Answer to Question #254302 in C++ for Fisiwe Shezi

Question

The following code is supposed to display the positive even numbers less than 12. That is, it will output the numbers

2, 4, 6, 8 and 10. However, there is a logical error in the code. Explain what the output of the code below will be.

Then write a small program including the code below and make the necessary changes to fix the code so that it

displays what it is intended to display. Ensure that your program works correctly. Only submit the program, not the

output.

Hint: Use variable diagrams to trace the program to help you find the logical error.

int x = 1;

while (x != 12)

{

cout << x << endl;

x = x + 2;

Answer 1

The output of this program of infinite sequence of odd numbers: 1 3 5 ...

To fix it one should initialized x to 2

#include <iostream>
using namespace std;

int main() 
{
    int x = 2;
    while (x != 12)
    {
        cout << x << endl;
    x = x + 2;
    }

    return 0;
}
