pointers to function
 

hey guys
i am using miracle c compiler on windows xp....
i am trying to figure out how does pointer to functions work.....
i have gone thru many tutorials but all have them failed to compile....

#include <stdio.h>



int sum(int x, int y)

{

   return x + y;

}



int product(int x, int y)

{

   return x * y;

}





int main()

{

   int a = 13;

   int b = 5;

   int result = 0;

   int (*pfun)(int, int);



   pfun = sum;

   result = pfun(a, b);

   printf("\npfun = sum   result = %d", result);



   pfun = product;

   result = pfun(a, b);

   printf("\npfun = product         result = %d", result);



}

//this source code is from

//http://www.java2s.com/Code/C/Function/Pointingtofunctions.htm

i get this error.......

C:\Program Files\Miracle C\work.c: line 21: Parse Error
'int (*pfun)(int, int)'
aborting compile

pls tell me wats wrong and also send me source code explaining the pointers to function

Re: pointers to function
 

It works on my Dev-cpp (mingw, gcc) compiler, and I can't see any problem with code, so it's probably something about your compiler.

so wat compiler do u suggest......

Miracle C is a horrible compiler. Trash it and get anything else, or you'll have to suffer through constant battles of perfectly valid code failing to compile or not working correctly.

Try Code::Blocks, Turbo C++, or Visual C++.

i am learning c
so how can i use visual c++,turbo c++......
pls can u suggest a compiler for windows.........
its urgent.....

>i am learning c
C++ compilers can compile C. Usually all you have to do is name the source file *.c instead of *.cpp.

>pls can u suggest a compiler for windows.........
I suggested three of them. They're all easy to install and use. Stop being lazy.

>its urgent.....
Not for me.
