20. Write a program in Ct+ to perform binary operator overloading following will be specification for the program. a) Create class comples b) Class complex contains private access modifier and variable n c) The public section of class complex has function get which accepts user input number: d) Overload operator + and add number input from user e) Overload operator and subtract number input from user f) Overload operator/and divide number input from user g) Overload operator * and multiply number input from user h) Finally display value of add, subtract, multiply and divide Description: Operator Overloading is a technique of polymorphism by which an operator {+, etc) can be used to do different types of operations. eg:t can be used to add two integers say a and b using sum =a+b similarly two floating point numbers say fa,fb by fs=fa+fb. In this example +,, operators are overloaded to add, subtract, multiply and divide two complex numbers. First a class named complex is created which has overloaded operators like + specified by a function 'complex operator +( complex c2) which can used to add two complex numbers like c3=c1+c2 where c1,c2 and c3 are complex numbers. The complete source in C++to implement operator overloading is provided below
