Simple Data Types

The built-in, simple data types in C++ are integral types, enumeration types, and

floating types. The integral types are char, short, int, long, and bool. The floating

types are float, double, and long double. All of these data types are called simple

or atomic because they are composed of single, indivisible values.

The range of values that can be stored in a simple, integral data type depends on

the number of bytes of storage assigned to the data type. C++ provides a unary

operator, sizeof, that returns the number of bytes in its operand. C++ does not

specify the number of bytes for any data type except
