Project 2.5 "MyString 2.5 Remember to try to find as many solutions as you can using pointer arithmetic like we modeled today in class with strlen, strcat, and strcpy as you can on this version of MyString Class description: A MyString class should behave much like the c++ string class. Your class should use a dynamically allocated char array to hold a character string. If the amount of memory allocated to the array is too small to complete some necessary task (e.g., assigning a new character string to the object) your object should automatically double its capacity until it is large enough to complete the task. If you discover that your object is using less than 25% of its capacity your object should shrink to half its capacity until it is using more that 25% of its capacity. Problem Statement: Implement the MyString class using a header and implementation file named MyString.h and MyString.cpp respectively. Make sure to properly test your code on your own by creating a test driver that tests every function created in the MyString class. Some members and functions have been changed a bit Deliverables proj2.5-MyString.h proj2.5-MyString.cpp proj2.5-testMain.cpp Memory Requirements: Your MyString should start with 3 bytes of allocated memory and should grow in size by doubling. So, we should be able to predict the capacity of your MyString as acquiring a pattern of 3, 6, 12, 24,.. bytes of memory depending of the number of characters stored. Attributes: int capacity the number of bytes currently allocated. This should always be at least size + 1. The extra byte is needed to store the NULL character. char "data character pointer that points to an array of characters.
