Constructor in C++
Any class needs to be instantiated. A constructor is a special function created by default, used to automatically initialize an object. A constructor is implicitly called whenever an object is created. A constructor is also used to initialize the data mem
# include<iostream.h>
class add
{
int n1,n2,res;
public:
add()
{
cout<<”Inside the default constructor”<<endl;
n1=n2=res=0;
}
void accept()
{
cout<<”Enter two numbers:” <<endl;
cin>>n1;
cin>>n2;
}
