Explanation
This C++ program defines a class named complex to represent complex numbers. The class has two private data members x and y which represent the real and imaginary parts of the complex number respectively.
The complex class also has a default constructor and a parameterized constructor that takes two arguments, real and imag. The parameterized constructor initializes the x and y data members of the object being created with the values passed as arguments.
The complex class also has a display method which prints the complex number in the format x+yi.
The complex class has overloaded the + operator using the operator+ method. This operator allows us to add two complex numbers.
In the main function, three complex objects c1, c2, and c3 are created. c1 is initialized with the values 3.2 and 2.5 using the parameterized constructor. c2 is initialized with the values 4.5 and 2.5 using the parameterized constructor.
The program then uses the overloaded + operator to add c1 and c2, and the result is stored in c3. Finally, the display method is used to print the values of c1, c2, and c3.
Output:
First Object:3.2+2.5i
Second Object:4.5+2.5i
-----------------------------------
Result:7.7+5i
This program adds two complex numbers, c1 and c2, and prints the result in the format x+yi. The result is stored in c3, which is also a complex object. The display the method is used to print the values of c1, c2, and c3.
