#include <stdio.h>

int main()
{
    int a,b,c;

    printf("I'm waiting for three characters: ");
    a = getchar();
    b = getchar();
    c = getchar();
    printf("The three characters are '%c', '%c', and '%c'\n",a,b,c);
    return(0);
}

Output

I'm waiting for three charcters: YXZ
The three characters are 'X', 'Y', and 'Z'

Notes

* Remember: getchar() is not an interactive function, neither is any function that reads stream input.
