Overloaded Constructor
A constructor that uses different signatures is called overloaded constructor.
since two explicit constructor with the same name , rational () , we say the constructor is overloaded.
class rational
{
private:
int num;
int denum;
public:
rational ( ):num(1 ),denum ( 1) // this is no argument constructor also called default argument constructor
{ }
rational (int n , int d ): num ( n) ,denum(d) // this is two argument constructor like overloaded constructor
{ }
Here is an example that will clear your idea about that topic.
Example
#include <iostream>
using namespace std;
class rational
{
private:
int num;
int dnum;
public:
rational():num(1),dnum(1)
{}
rational(int n ,int d):num(n),dnum(d)
{ }
void get ()
{
cout<<"enter numerator";
cin>>num;
cout<<"enter denomenator";
cin>>dnum;
}
void print ()
{
cout<<num<<"/"<<dnum<<endl;
}
void divide(rational r1,rational r2)
{
num=r1.num*r2.dnum;
dnum=r1.dnum*r2.num;
}
};
void main ()
{
rational r1,r2,r3;
rational r4(2,3),r5(4,5),r6;
r1.get();
r2.get();
r3.divide(r1,r2);
r6.divide(r4,r5);
r3.print();
r6.print();
}

you can solve this program by using add instead of divide by done just some changes in this program.
· use + sign instead of / .
· use add word instead of divide
· you can use any arithmatic operator to done this program.
