    Constant member functions are those functions that can not modified the object state. Constant member functions are “read only”. Constant data member function can not change data member. To declare a constant member function, place the const keyword after the closing parenthesis of the argument list. The const keyword is required in both the declaration and the definition.
    class className{
    returnValue Function() const;
    returnValue className:: function() const{
    class Student{
    int getRollNo() const {
    return rollNo;
