Question
Joesph Moore,

Hi I had a question about this program i am trying to write for my programming class. The program I am trying to write is:

Write a program that asks the user for the race time in minutes and seconds for a runner. Then compute and display the speed in feet per second and in meters per second. Write and call a function that displays instructions to the user. Also write a function that takes minutes and seconds as arguments and prints the results.

The instructions part is easy that is simply a printf statement. I dont understand what he means by taking minutes and seconds as arguments though.

#include <stdio.h>
#define meter 3282
#define foot 5280

int
main (void)
{
       double  minutes,
               seconds,
       printf("$ track\n");
       printf("This program will ask for the minutes and seconds for the time it took for a runner to run a mile. The program will then calculate the feet per second and meters per second for that runner.\n");
       printf("Minutes for the runner: ");
       scanf("%lf",&minutes);
       printf("Seconds for the runner: ");
       scanf("%lf",&seconds);

       totalseconds=seconds+(minutes/60)


       return(0);
}

This is what I have so far...

Answer
You are being asked to write a function which you call that does the work.  Just like your main function here is a function which takes no arguments, you must write a function which takes some arguments (or parameters) such as:

   void foo(int bar);

The above function template takes an integer as a parameter.  Your program would call a function to ask for and store the data, then call a function with the input and print the results.
