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.
