Write a class BCheckString that is derived from the STL string class. This new class will have two member functions: A) A BCheckString(string s) constructor that receives a string object passed by value and passes it on to the base class constructor.B) An char operator[](int k) function that throws a BoundsException object if k is negative or is greater than or equal to the length of the string. If k is within the bounds of the string, this function will return the character at position k in the string. You will need to write the definition of the BoundsException class. Test your class with a main function that attempts to access characters that are within and outside the bounds of a suitably initialized BCheckString object.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Write a class BCheckString that is derived from the STL string class. This new class will have two member functions:
A) A BCheckString(string s) constructor that receives a string object passed by value and passes it on to the base class constructor.
B) An char operator[](int k) function that throws a BoundsException object if k is negative or is greater than or equal to the length of the string. If k is within the bounds of the string, this function will return the character at position k in the string.
You will need to write the definition of the BoundsException class. Test your class with a main function that attempts to access characters that are within and outside the bounds of a suitably initialized BCheckString object.
