C++ program to Add two Complex number passing objects to function

What are Functions ?

Function is a block of statements that performs some operations. All C++ programs have at least one function – function called “main()”. This function is entry-point of your program.

A function declaration tells the compiler about a function’s name, return type, and parameters. A function definition provides the actual body of the function.

Defining a Function : :

The general form of a C++ function definition is as follows:

return_type Function_Name( list of parameters )
{
//function’s body
}

• return_type : suggests what the function will return. It can be void, int, char, some pointer or even a class object.
• Function_Name : is the name of the function, using the function name it is called.
• Parameters : are variables to hold values of arguments passed while function is called. A function may or may not contain parameter list.
• Function body : is he part where the code statements are written.

/*  C++ program to Add two Complex number passing objects to function  */

#include<iostream>
using namespace std;

class complex
{
        int re,im;
        public:
                void get()

}

int main()

        c1.get();
        cout<<"\nEnter 2nd complex no.: \n";
        c2.get();
        cout<<"\nThe 1st complex no. is :: ";
        c1.disp();
        cout<<"\nThe 2nd complex no. is :: ";
        c2.disp();

        c3.sum(c1,c2);

        cout<<"\nThe Sum of two complex no.s are :: ";
        c3.disp();

        return 0;

}

OUTPUT : :

/*  C++ program to Add two Complex number passing objects to function  */

Enter 1st complex no.:

Enter Real Part :: 1

Enter Imag. Part :: 2

Enter 2nd complex no.:

Enter Real Part :: 3

Enter Imag. Part :: 4

The 1st complex no. is :: 1+2i

The 2nd complex no. is :: 3+4i

The Sum of two complex no.s are :: 4+6i

Process returned 0
