Discussion Forum : Declarations and Initializations - Point Out Errors (Q.No. 5)
5.
Point out the error in the following program.
#include<stdio.h>
int main()
{
int (*p)() = fun;
(*p)();
return 0;
}
int fun()
{
printf("IndiaBix.com\n");
return 0;
}
Answer: Option
Explanation:
The compiler will not know that the function int fun() exists. So we have to define the function prototype of int fun();
To overcome this error, see the below program
#include<stdio.h>
int fun(); /* function prototype */
int main()
{
int (*p)() = fun;
(*p)();
return 0;
}
int fun()
{
printf("IndiaBix.com\n");
return 0;
}

(*p)() ;
How these two lines will work?
int (*p)() = fun;
(*p)() ;
How these two lines will work?
