Function Pointer in C

 A function pointer is like a note that holds the location of a function instead of holding data.

 A function pointer is a special kind of pointer that stores the address of the function.

 It allows you to call a function indirectly through the function.

 The function pointer holds the memory address of the function instead of  the data.

Syntax of Function Pointer in C 

 Return type(*function pointers variable name)(parameters);

Example:

int(*func)(int a,int b);

Program for Function pointer in C 

 // Program for Function pointer in C
 #include<stdio.h>
// Function declarations
          int add(int A, int B);
		  
          int main() {
// Declare a function pointer for functions taking two ints and returning int
          int (*C)(int, int);
          C = add;
          int sum = C(5, 3);


          printf("Result of add function: %d\n", sum);
          return 0;
          }
          int add(int a, int b) {
          return a + b;
}

Output:

Result of add function: 8
