Objectorientedprogrammingusingc++Lab Cse Section Regd - No Week Date Programnumber Titleofexperiment Sourcecode

This document contains the source code and outputs for 4 programs written in C++. The first program uses friend functions to add two numbers stored in different classes. The second program uses pointers to read and print array elements. The third program extends this to also print the sum of the array elements. The fourth program calculates the factorial of a number using a friend function.

TitleofExperiment:perform addition of 2 no in c++ using friend function on 2 classses

Sourcecode:
#include<iostream>
using namespace std;
class B;
class A
{
int a;
public:
void getdata1()
{
cout<<"enter a";
cin>>a;
}
friend void sum(A ob1,B ob2);
};
class B
{
int b;
public:
void getdata2()
{
cout<<"enter b";
cin>>b;
}
friend void sum(A ob1,B ob2);
};
void sum(A ob1,B ob2)
{
cout<<ob1.a+ob2.b;
}
int main()
{
A ob1;
B ob2;
ob1.getdata1();
ob2.getdata2();
// cout<<"enter values";
//cin>>ob1.a>>ob2.b;
sum(ob1,ob2);
return 0;
}
