Write a C++ program which should show the constructor overloading

#include<conio.h>
#include<string.h>
#include<iostream.h>
class abc
{
  private:
    int n;
  public:
abc()
    {
      n=0;
    }
abc(int x)
    {
      n=x;
    }
    void getdata()
    {
      cout<<"Enter the no:";
      cin>>n;
    }
    void show()
    {
      cout<<"\n"<<"Sum is: "<<n;
    }
abc add(abc,abc);
};
abc::add(abc n1,abc n2)
{
abc temp;
  temp.n=n1.n+n2.n;
  return(temp);
}
void main()
{
abc n1(50);
abc n2,n3;
  clrscr();
  n2.getdata();
  n3=n3.add(n1,n2);
  n3.show();
  getch();
}

 


OUTPUT
Enter the no:5
Sum is : 55
