C program to show function pointers as a parameter
A simple C program to show function pointers as parameter
// A simple C program to show function pointers as parameter
#include <stdio.h>
// Two simple functions
void fun1() { printf("Fun1\n"); }
void fun2() { printf("Fun2\n"); }
// A function that receives a simple function
// as parameter and calls the function
void wrapper(void (*fun)())
{
fun();
}
int main()
{
wrapper(fun1);
wrapper(fun2);
return 0;
}
Fun1
Fun2
Like normal data pointers, a function pointer can be passed as an argument and can also be returned from a function.For example, consider this C program where wrapper() receives a void fun() as parameter and calls the passed function.
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
