Friend Funtion

Write a Program to find sum of two complex no.s using Friend Function.

#include<iostream> using namespace std; class complex_add { public: int x,y; void input() { cout<<"Enter the real & imaginary part of complex no.:"; cin>>x>>y; } friend void show(complex_add,complex_add,complex_add); }; void show(complex_add p,complex_add q,complex_add r) { cout<<"First complex no.:= "<<p.x<<"+i"<<p.y<<endl; cout<<"Second complex no.:= "<<q.x<<"+i"<<q.y<<endl; cout<<"Sum of complex no.:= "<<r.x<<"+i"<<r.y<<endl; } int main() { complex_add a,b,s; a.input(); b.input(); s.x=a.x+b.x; s.y=a.y+b.y; show(a,b,s); return 0; }
