scanf() does not output anything, it reads from the standard input.

Maybe can you share some code or explain in more detail what you're after?

Here's a silly example using scanf() and printf():

#include <stdio.h>

int main()
    int age;
    printf("How old are you? ");
    scanf("%d", &age);
    if (age >= 18)
        printf("You are legally and adult.\n");
        printf("You are legally not an adult yet.\n");

    return 0;
