Question

Please use C programming to write a code segment as an answer. Instead of using an while-loop like the following code, please implement a code segment by using a do-while loop. What is the output of the code?

#include <stdio.h>

void main()

{

       int i = 0;

       while (i < 5);

       {

              printf(“%d ”, ++i);

       }

}

Answer 1

Actually the given code has an infinite loop.
Because the while statement ends with a semi column.

If we remove the semi column at the end of while statement then it will produce "1 2 3 4 5" as its output.

Code with do-while loop:
--------------------------
#include <stdio.h>
void main()
{
       int i = 0;
       do
       {
              printf("%d ", ++i);
       }while (i < 5);
}
