C++ constantssyntax
Constant values are fixed values that do not change during program execution. These fixed values are also called literals.
Constants can be any basic data type, which can be divided into integers, floating-point numbers, characters, strings and Boolean values.
Constants are like regular variables, except that the value of a constant cannot be modified after it is defined.
