Is there a 128 bit integer in C++?

Question

I need to store a 128 bits long UUID in a variable. Is there a 128-bit datatype in C++? I do not need arithmetic operations, I just want to easily store and read the value v

Answer 1

Checkout boost's implementation:

#include 

using namespace boost::multiprecision;

int128_t v = 1;

This is better than strings and arrays, especially if you need to do arithmetic operations with it.
