6 Overloaded Operators Lab Report and Source Code
Assignment: Lab 6 Overloaded Operators
Description: This lab is to introduce students to the concept of
operator overloading as member functions of a class. This will be done in the
context of creating a class that will perform four basic mathematical
operations on complex numbers.
The C++ compiler has defined operators for all the arithmetic and
assignment operations for its native data types, such as integer, float,
double, and so forth. However, for user-defined data types, such as classes and
structures, these operations are undefined.
C++ allows the programmer to create new definitions for these
operators so that they can operate specifically on these user-defined data
types. Which set of operators is actually called and implemented is decided
during the compilation, and it is based on the data types of the operands
involved in the operation.
The ability to define a new set of data-type, dependent operations
on existing operators, or functions, is called operator overloading.
