What is constructor explain with example?

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.
