Each variable in C++ has a specific type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory; and the set of operations that can be applied to the variable. The name of a variable can be composed of letters, digits, and the underscore character. A variable is a way of referring to a memory location used in a computer program. This memory location holds values- perhaps numbers or text or more complicated types of data like a payroll record.
