The operand of a predefined operator in C + + can only be a basic data type. In practice, however, similar operations are required for many user-defined types, such as classes. These operators must be redefined in C + +, giving the existing

The operations object of a predefined operator in C + + can only be the base data type. In practice, however, similar operations are required for many user-defined types, such as classes. These operators must be redefined in C + +, giving the

The 4th Chapter weaves the statement into a programHaving learned the various data types in C + +, you know how to use various data types to define variables to describe things in the real world. Now, we can write a payroll statistics program
