C++ variable typessyntax
A variable is actually just the name of a storage area that the program can operate on. Each variable in C++ has a specified type. The type determines the size and layout of variable storage. Values within this range can be stored in memory, and operators can be applied to variables.
Variable names can consist of letters, numbers, and underscore characters. It must start with a letter or underscore. Uppercase letters and lowercase letters are different because C++ is case-sensitive.
