Fastest and Smallest Fixed width integer types in C++ (int_least8_t, int_fast8_t, ...)

In this article, we are going to learn about the Fastest and Smallest types of Fixed width integer types in C++ such as int_least8_t, int_fast8_t and more.

The basic data types in C or C++ are char, short, int, and long, each of which allows 1, 2, or 4,8 bytes in memory, respectively. However, this byte can vary depending on the compiler, operating system, or hardware used.

On a 32-bit compiler, the Long data type allocates 4 bits in memory, whereas, on a 64-bit compiler, it allocates 8 bytes in...
