Answer to Question #172748 in C++ for Panjumin

Question

Create the class Complex that has floating point data members for storing real and imaginary parts and perform complex number addition. The class Complex has the following member functions: Complex() - Null constructor invokes when an object is created Complex(float, float) - Parameterized constructor to set the specified value of real and imaginary parts in object friend complex sum(complex, complex) - Friend function to perform complex number addition and return complex number display() - Function to display complex number object

Answer 1

#include<iostream>

using namespace std;

class complex

{

int real,imag;

public:

void set()

{

cout<<"enter real and imag part";

cin>>real>>imag;

}

friend complex sum(complex,complex);

void display();

};

void complex::display()

{

cout<<"the sum of complex num is"<<real<<"+i"<<imag;

}

complex sum(complex a,complex b)

{

complex t;

t.real=a.real+b.real;

t.imag=a.imag+b.imag;

return t;

}

int main()

{

complex a,b,c;

a.set();

b.set();

c=sum(a,b);

c.display();

return(0);

}
