Address of a function in C or C++
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 ( "w3wiki" ); } 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
