Question

i am enthusiast and new in programming trying this simple c language code and compile it with gnu compiler. here is my code:

/*simple program:trying to printf string and get a letter*/


#include "stdio.h"

int main()
{
    int i=0;
    char c;

    while(i++<100){
        if(i % 2)
            printf("%C this is even number",i);
        if(i==50){
            c=getchar();
            printf("you enter %c letter",c);
            }
    }
    return 0;
}

however when i compile it with gcc and run in terminal, it doesnt show anything,no error and no warning. i tried to figure it out by changing the way my code behave but still not work. is it the code that wrong or gcc have bug or may be i miss about something?

Answer 1

Try to put a newline at the end of printf text:

printf("%C this is even number\n",i);

Also i is an int so use the %d format:

printf("%d this is even number\n",i);

Edit: I just tested this with the changes and it works for me.
