Write a c++ program that explaining member function overloading

#include<iostream.h>
#include<conio.h>
class RECT{
int l;
int b;
public:
void getDAta()
{
cout<<"Get length and Breadth";
cin>>|>>b;
}
void getData(int l1,int b1)
{
l=|1;
b=b1;
}
void getData(int a1,int b1,int c1,int d1)
{
l=a1+b1;
b=c1+d1;
}
void printArea()
{
cout<<"Area of Rectangle"<<|*b;
}
};
void main()
{
RECT r1,r2;
r1.getData();
r1.printArea();
r2.getData(2,3,3,5);
r2.printArea();
getch();
}
