    Question Header file creation problem

    I get an error when compiling my source file for the header,

    [Linker Error] Undefined reference to 'WinMain@16'

    Here is my header code:

    #define Pi 3.14159265358979323846

    extern double sin( double ); // Sine of an angle
    extern double cos( double ); // Cosine of an angle
    extern double tan( double ); // Tangent of an angle
    extern double sinh( double ); // Hyperbolic Sine of an angle
    extern double PowerOf( double, int ); // X to the power of Y
    extern double Factorial( double, int ); // Factorial of double value



    Here is the beginning of the source file:


    #include <stdio.h>
    #include <stdlib.h>
    #include <trigs.h>




    /************************************************** ****************************
    The factorial funtion will use a while loop to determine the factorial value of
    a number which will be used in the trig loop for series expansion as x/n! etc.
    ************************************************** *****************************/

    double Factorial( double value, int x)
    {
    if(x == 0) return 1;
    else
    {
    while( x > 1)
    {
    value = value / x--;
    }
    }
    return value;
    }



    etc. etc.

    Any ideas on why I'm getting a linker error?

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
