stduint64t
stduint64t is a type defined in the C++ standard library, specifically within the <cstdint> header. It represents an unsigned integer type with a guaranteed minimum size of 64 bits. This means it can store values from 0 up to at least 2^64 - 1. The "stduint" prefix indicates it's a standard unsigned integer, and "64t" specifies its size.
The primary purpose of stduint64t is to provide portability and predictability when dealing with large integer
This type is particularly useful in scenarios involving large numerical data, such as file sizes, network packet
