C++ Programming - OOPS Concepts - Discussion

What are the keys using inheritance?

Constructor is used to initialize the objects and the name of the constructor is same as the name of the class. And we can say construct the values of data members.

for eg. class demo
{
int a;
demo()
{
a=0
}
};

In this example, demo is the class and the name with parentheses is the constructor.
Whenever we create the object of the class demo the constructor will be called and assign value 0 to variable a.

What is constructor explain with example?

The friend is not a constructor because friend is an access specifier and they used in asp.net.

Friend is a function.

The friend is not a constructor because it is a function.

We can pass the value as a parameter of the constructor, but it's not a type of constructor.

Friend is a function not constructor.

Remaining options are types of constructor and friendly is a function.

Default, Parameterized, and Copy constructor are the constructor types of C++.
