If you want a message to appear on standard output,
which asks the user for input,
then use fflush(stdout) after the message code,
before the input code.

/* BEGIN new.c */

#include <stdio.h>

int 
main(void)
{
    int integer;
    
    printf("Enter an integer: ");
    fflush(stdout);
    if (scanf("%d", &integer) == 1) {
        printf("\nThe integer is %d\n", integer);
    } else {
        puts("\nTry harder next time!");
    }
    return 0;
}

/* END new.c */
