1) Write a simple object oriented program that get and show 2 numbers.

 source code: OOP1.cpp

#include<stdio.h>
#include<conio.h>
#include<iostream.h>
class simple
{
int a,b;
public:
void get(int m, int n)
{
a=m;
b=n;
}
void show()
{
cout<<" a: "<<a<<" b: "<<b;
}
} ;
void main()
{

clrscr();
cout<<"object oriented program: ";

simple ob1, ob2;

ob1.get(10,20);

ob2.get(-5, -15);

ob1.show();

ob2.show();

getch();
}

output:

 object oriented program:

a : 10 b:20

a: -5 b: -15
