Answer to Question #332843 in C++ for Padi Tlhabane

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

#include <iostream>


using namespace std;


int main()
{
	//int x = 1;//not correct initialization leads to endless loop
	//Change x on another value
	int x = 2;
	while (x != 12) 
	{
		cout << x << endl;
		x = x + 2;
	}
}
