Complex number using object as argument

Complex number using object as argument

Aim:
To write a C++ program to add two complex numbers using object as argument.
Algorithm:
Step 1: Create a class as complex.
Step 2: Declare the data members as real and img.
Step 3: Declare the member functions as
void getdata()
void show()
void sum(complex c1,complex c2)
Step 4: getdata() method is used to get the values .
Step 5: show() method is used to display the values.
Step 6: sum() method is used to perform addition operation using object as argument.
Step 7: In main, create the object for Complex class.
Step 8: Call the function using objectname.functionname();
Program:
#include<iostream.h>
#include<conio.h>

class complex
{
int real;
int img;
public:
void getdata()
{
cout<<"Enter the real and img part";
cin>>real>>img;
}
void show()
{
cout<<"\n"<<real<<"+"<<img<<"i"<<"\n";
}
void add(complex c1,complex c2);
};

void complex::add(complex c1,complex c2)
{
real=c1.real+c2.real;
img=c1.img+c2.img;
}

void main()
{
clrscr();
complex c1,c2,c3;
c1.getdata();
c2.getdata();
c3.add(c1,c2);
cout<<"The complex number of c1:";
c1.show();
cout<<"The complex number of c2:";
c2.show();
cout<<"The result is:";
c3.show();
}

Output:

Enter the real and img part 4 5
Enter the real and img part 2 3

The complex number of c1:
4+5i

The complex number of c2:
2+3i

The result is:
6+8i
