Special properties of the constructor function is given below
Explanation:
- Constructors are used to initialize the class.it means that the object is initialised.
- The name of the constructor should have the same name as the class.it means a constructor's name will have the class name.
- The constructor never has a type of return. This means that there is no type of constructor return, even void.
- For example :
#include<iostream> // header file
using namespace std; // namespace
class abc // class abc
{
abc() // constructor
{
cout<< " hello:";
}
};
void main() // main method
{
abc on; // call default constructor
}
