    Hi all... this bit of code compiles fine with mingW, but gives me no output!

    Code:
    #include <stdio.h>
    #include <math.h>
    #include <float.h>
    #include <stdlib.h>
    
    long cap_reac();
    long c, freq, a;
    
    int main()
    {
    printf("input the cap value...\n");
    scanf("l%", &c);
    printf("input the frequency...\n");
    cap_reac();
    cap_reac()
    }
    { long c, freq, a;
    a =(159.2/(c * freq));
    printf("%l equals... " , a);
    }

    We've got quite a few problems here.

    You define some global variables then try to define them again within the function.
    The prototype says the function is a long and where you define the function you havent specified what type it is.
    You've closed a bracket where the function definition is, you should have closed it at the end of main().
    There is no scanf call to get the frequency from the user.

    Needs a bit of work.

    After compile time errors come the run time errors. The latter don't generate messages, just black screens or lockups. Then you get to use (or write) a debugger.
