Exercise P7.15. Exercise P7.14 demonstrated how to use the string and vector classes to implement resizable arrays. In this exercise, you should implement that capability manually. Allocate a buffer of 1,000 characters from the heap (new char[1000]). Whenever the buffer fills up, allocate a buffer of twice the size, copy the buffer contents, and delete the old buffer. Do the same for the array of char* pointersstart with a new char*[100] and keep doubling the size.
