Chapter 16, Problem 1PC

String Bound Exceptions

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.

C++ Struct Pointers Help: I have a file called names.txt. Write a program that reads each line and then store the name and nickname under an individual pointer to the class Person. names.txt: Norman, Normie Justine, Jussy Richard, Dick Shelley, Shell class Person {     public:         string name;          string nickname;       Person(string name, nickname) {         this->name=name;         this->nickname = nickname;      } };   Print out each pointer's name and nickname to verify that it has been stored.
IN C++ Write code that: creates 3 integer values - one can be set to 0, the other two should NOT multiples of one another (for example 3 and 6, or 2 and 8) take you largest value and perform a modulus operation using the smaller (non zero) value as the divisor print out the result. create an alias for the string type call the alias "name" then create an instance of the "name" class and assign it a value using an appropriate cout statement - print out the value Please screenshot your input and output, as the format tends to get messed up. Thank you!
