Thread: Code compiles but doesn't run

I changed main to int main(), although it really shouldn't have a big impact on the output but lets just use int main() for the sake that int main() is how the standard wants it.

I added
#include <stdlib.h>
to the code because system() comes from stdlib.h
I find it odd that your compiler compiled it without including stdlib.h

If problems persist it may have something to do with the way your compiler links perhaps.


here is the code, (modified)

Code:

#include <stdio.h>
#include <stdlib.h>
/*Structure declaration*/
struct employee
{
     long id_number;
     float wage;
     float hours;
     float overtime;
     float gross;
};

/*Variable declaration (global)*/
struct employee data[5] = { {98401, 10.60}, {526488, 9.75}, {765349, 10.50},
{34645, 12.25}, {127615, 8.35} };

struct employee get_hours (struct employee data[])
{
     int temp, i = temp;

     for (temp=1; temp<6; ++temp)
     {
         printf ("Enter employee #%06d hours worked: ", data[temp-1].id_number);
         scanf ("%f", &data[temp-1].hours);
     }
     return (data[i]);
}

struct employee calculate_overtime (struct employee data[])
{
     int temp, i = temp;

     for (temp=1; temp<6; ++temp)
     {
         if (data[temp-1].hours > 40)
             data[temp-1].overtime = data[temp-1].hours - 40;
         else
             data[temp-1].overtime = 0;
     }
     return (data[i]);
}

struct employee calculate_gross (struct employee data[])
{
     int temp, i = temp;

     for (temp=1; temp<6; ++temp)
     {
         if  (data[temp-1].overtime > 0)
             data[temp-1].gross = (data[temp-1].wage * 40) +
             ((data[temp-1].wage * 1.5) * data[temp-1].overtime);
         else
             data[temp-1].gross = (data[temp-1].wage * data[temp-1].hours) +
             ((data[temp-1].wage * 1.5) * data[temp-1].overtime);
     }
     return (data[i]);
}

void output (struct employee data[])
{
     int temp;

     printf ("\n\n");
     printf ("--------------------------------------------------------\n");
     printf ("Clock #    Pay Rate     Hours      OT      Gross Pay\n");
     printf ("--------------------------------------------------------\n");

     for (temp=1; temp<6; ++temp)
     {
          printf ("%06d     $%5.2f      %5.1f     %5.1f     $%6.2f\n",
          data[temp-1].id_number, data[temp-1].wage, data[temp-1].hours,
          data[temp-1].overtime, data[temp-1].gross);
     }
}


int main ()
{
     int i;  

     /*Execute functions*/
     for (i=1; i<6; ++i)
     {
          get_hours (data);
          calculate_overtime (data);
          calculate_gross (data);
     }
     
     output (data);

     printf ("\n");
     system("PAUSE");
	 return 0;
}

here is the output I got, if this is not correct then check the code...

Yup, looping problem. Look at this:

Code:

//in int main
     for (i=1; i<6; ++i)
     {
          get_hours (data);
          calculate_overtime (data);
          calculate_gross (data);
     }

//in get hours
     for (temp=1; temp<6; ++temp)
     {
         printf ("Enter employee #%06d hours worked: ", data[temp-1].id_number);
         scanf ("%f", &data[temp-1].hours);
     }
