Address of a function in C or C++

  • Difficulty Level : Easy
  • Last Updated : 20 May, 2018

We all know that code of every function resides in memory and so every function has an address like all others variables in the program. We can get the address of a function by just writing the function’s name without parentheses. Please refer function pointer in C for details.

Address of function main() is 004113C0
Address of function funct() is 00411104

In C/C++, name of a function can be used to find address of function.




// C program to addresses of a functions
// using its name
#include<stdio.h>
  
void funct()
{
    printf("GeeksforGeeks");
}
  
int main(void)
{
    printf("address of function main() is :%p\n", main);
    printf("address of function funct() is : %p\n", funct);
    return 0;
}
Output:
address of function main() is :0x40053c
address of function funct() is : 0x400526
