Chapter 11.1, Problem 11.38CP
Explanation of Solution
Data Type conversion:
- In C++, some special operator functions are used to convert a class object to any other data type.
- The type conversion of data happens behind the scenes with the built-in data types.
- When a function provides an automatic type conversion then it is called as operator functions.
- Objects are automatically converted to other data types with the use of operator function. This gives the assurance that an object data is properly converted.
Syntax:
The syntax of object conversion is as follows:
class_name::operator data_type()
Example:
The below code describes the data type conversion of on operator function:
/*operator function that converts...
