hello all,
please help me to create the dynamic link library code linking with C using 2dimensional array...

#include "stdio.h"
#include "math.h"
#define PI 3.1415

printf("k[%d,%d]=w=%f\t",x,y,w);
}
else
printf("k[%d,%d]=w=%f\t",x,y,0);
}
}
}
this is my example program so plz tell me how to creat DLL for this program/.. thank u
