#include <stdio.h>


int main() {
    int distance, time, speed ;
    printf("Enter the number of furlongs traveled : ");
    scanf("%d" , &distance);
    printf("Enter the number of fortnights it took : ");
    scanf("%d" , &time);

    speed = distance / time ;

    printf("Your speed is '%d' furlongs-per-fortnight", &speed);
   return 0;
}

I keep getting an error warning in my code as follows...

speed.c:13:57: warning: format specifies type 'int' but the argument has type
'int *' [-Wformat]
printf("Your speed is '%d' furlongs-per-fortnight", &speed);
~~ ^~~~~~

format specifies type 'int' but the argument has type
'int *'

That says it all, really. The %d specifies that an argument of type int should be passed, but you passed &speed - an address of speed, in other words - int* instead of int.
