error with function pointers usage in C - function

Question

#include <stdio.h>
#include <string.h>
void func1 (void) { printf( "1\n" ); }
void func0 (void) { printf( "0\n" ); }
typedef struct {
void (*func0)(void);
void (*func1)(void);
}mainJT;
static const mainJT coreJT = {
core_func0,
core_func1
};
mainJT currJT;
int main()
{
currJT=coreJT;
coreJT.core_func0();
getchar();
return 0;
}
Please help me fix the errors, I am sure I am making some obvious mistakes. Thanks.

Answer 1

Your question isn't quite clear but I see what I can find.
typedef struct {
void (*func0)(void);
void (*func1)(void);
} mainJT;
Here you are declaring a struct with function pointer members func0 and func1. Then you are trying to define a coreJT variable via an initializer list:
static const mainJT coreJT = {
core_func0,
core_func1
};
But this doesn't work, because there are no functions called core_func0 or core_func1!
Also you try to call
coreJT.core_func0();
which is also incorrect since your struct doesn't have a member of name core_func0.
For a possible solution try renaming your functions like so:
void core_func1 (void) { printf( "1\n" ); }
void core_func0 (void) { printf( "0\n" ); }
and call your function pointer by
coreJT.func0();

i see lot of errors:
for eg: the correct way of initializing a structure is :
/* Define a type point to be a struct with integer members x, y */
typedef struct {
int x;
int y;
} point;
/* Define a variable p of type point, and initialize all its members inline! */
point p = {1,2};
so your part of the code is :
mainJT coreJT = {
core_func0;
core_func1;
};
completely wrong.
also where are the functions core_func1 core_func0 are declared and defined .i cannot see them.
i guess you first need to go through structures in c
