How to initialize a pointer to a specific memory address in C++ [duplicate]

Question

An interesting discussion about this started here but no one have been able to provide the C++ way of doing:

#include <stdio.h>

int main(void)
{
  int* address = (int *)0x604769; 
  printf("Memory address is: 0x%p\n", address);

  *address = 0xdead; 
  printf("Content of the address is: 0x%p\n", *address);

  return 0;
}

What is the most appropriate way of doing such a thing in C++?

Answer 1

In C++, always prefer reinterpret_cast over a C-cast. It's so butt ugly that someone will immediately spot the danger.

Example:

int* ptr = reinterpret_cast<int*>(0x12345678);

That thing hurts my eyes, and I like it.

Answer 2

There is NO standard and portable way to do so. Non-portable ways may include reinterpret_cast(someIntRepresentingTheAddress).
