A question on C

[salilgk]

Hello
I am trying to make my function pointer assignment program works. But facing some problem in compilation.

>>START FILE mytest.h

#ifndef WIBBLE_INC
#define WIBBLE_INC


struct mystruct
{
int (*add)(int,int);
int (*sub)(int,int);
};

extern const struct mystruct mstr;

#endif


<< END OF FILE mytest.h

>>START FILE mytest.c

include "mytest.h"


static int add(int x, int y)
{
return x+y;
}

static int sub(int x, int y)
{
return x-y;
}

const struct mystruct mstr={add,sub};

<<END OF FILE mytest.c

This while compiling I am getting the following error

cc -c -o mytest.o mytest.c
mytest.c:2: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before string constant
mytest.c:15: error: variable âmstrâ has initializer but incomplete type
mytest.c:15: error: âaddâ undeclared here (not in a function)
mytest.c:15: warning: excess elements in struct initializer
mytest.c:15: warning: (near initialization for âmstrâ)
mytest.c:15: warning: excess elements in struct initializer
mytest.c:15: warning: (near initialization for âmstrâ)

What could be the problem

thanks in advance

Where you have "include" you should have "#include" (i.e. put a hash sign at the start of the line). Also, where you need square brackets after "mystr" (i.e. "mystr[]") to declare it as an array (assuming you want to do that).

oops .. my bad ... yes # was missing in the include statement ... switching between scripting and compiled programming makes life tough thanks for the pointers
