Write a c++ program that includes all arithmetic operation

#include<iostream.h>
#include<conio.h>
class Number
{
private:
int n;
public:
void getNumber()
{
cout<<"Get Number";
cin>>n;
}
void print Number()
{
cout<<"n="<<n<<"\n";
}
friend void add(Number A,Number B);
friend void subtract(Number A,Number B);
friend void multiply(NUmber A,Number B);
friend void divide(Number A,Number B);
};
void add(Number A,Number B)
{
int tot;
tot=A.n+B.n;
cout<<"Total of two object="<<tot<<"\n";
}
void subtract(Number A,Number B)
{
int tot;
tot=A.n-B.n;
cout<<"Subtraction or two object="<<tot<<"\n";
}
void multiply(Number A,Number B)
{
int tot;
tot=A.n*B.n;
cout<<"Multiplication of two object="<<tot<<"\n";
}
void divide(Number A,Number B)
{
int tot;
tot=A.n/B.n;
cout<<"Division of two object="<<tot<<"\n";
}
void main()
{
Number X,Y;
clrscr();
X.getNumber();
Y.getNumber();
add(X,Y);
subtract(X,Y);
multiply(X,Y);
divide(X,Y);
getch();
}

Output: 
Get Number 23 3
Get NumberTotal of two object=26
Subtraction of two object=20
Multiplication of two object=69
Division of two object=7
