Project Description: You are given two files mystring1.h the document and mystring1.cpp the document which define a String class implemented by using static array as the data member. The purpose of this assignment is to rewrite this class by replacing the static array with a pointer (dynamic array). You are required to modify the String class accordingly: Data: we wish to allow our String class to accommodate strings of different sizes. To that end, instead of storing a string's characters in a fixed-size array, each String object should contain the following data as part of its internal representation: (1) a character pointer meant to point to a dynamically-allocated array of characters. (2) a length field that will hold the current length of the string at any given moment. Operations: same as the methods in String class, plus the "big three"( destructor, copy constructor, and assignment operator overloading). Modularity: The String class code must be put in its own module, i.e., a file mystring2.h (the header file) should hold the class definition (use conditional compilation directives) and a file mystring2.cpp (the implementation file) should hold the method definitions
