C++ supports two primitive floating point types: float and double. These are based on the IEEE 754 standard, which defines a binary standard for 32-bit floating point and 64-bit double precision floating point binary-decimal numbers. IEEE 754 represents floating point numbers as base 2 decimal numbers in scientific notation. An IEEE floating point number dedicates 1 bit to the sign …

In the C and C++ programming languages, an include guard, sometimes called a macro guard, is a particular construct used to avoid the problem of double inclusion when dealing with the #include directive. The addition of include guards to a header file is one way to achieve this. pragma once is a non-standard but widely supported preprocessor directive designed to …
