Task of reinterpret cast operator

reinterpret_cast is a C++ cast operator that converts one type into a completely different type by reinterpreting the bit pattern, without any run-time check or value conversion. It is used for conversions between unrelated pointer types, and between pointers and integers.

Syntax: reinterpret_cast<new_type>(expression)

#include <cstdint>

int x = 65;
int *ip = &x;
char *cp = reinterpret_cast<char*>(ip);            // view int memory as bytes
uintptr_t addr = reinterpret_cast<uintptr_t>(ip);  // pointer to integer

It is unsafe and non-portable. It cannot remove const (that needs const_cast), and it should be used only for low-level work such as hardware access or handling raw memory.
