Thread: Is this code snippet wrong

i want this code to keep executing until i enter 'n'. it sort of work in the sense that the loop exit when i enter 'n' and the first loop is executed ok but when i enter 'y' the two print statement is printed twice on the output.

Code:

#include <stdio.h>


int main()
{
    char a='y';
    while(a!='n')
    {
                 printf("testing testing testing");
                 printf("do you want to continue y or n");
                 scanf("%c",&a);
    }
}

Enter-key is a character too. If you don't want to read enter-key, you need to change your scanf so that it will skip enterkey:

Code:

scanf(" %c", &a);
