Home-made string class constructor
I have to construct a class for strings. C++ already has one, but my assignment is a home-made version. I am very lost as to how to make the constructor work. I have toyed with a few things, but I was given a header file to follow and I have no clue what to do. Any help would be appreciated.
I am clueless as to what to do. The constructor seems to be giving me the most trouble, I am not even sure where to start. All the other parts of the assignment seem possible, but the constructor is confusing me with the Capacity, Length, and * Mem.
unsigned Capacity; // Number of memory locations reserved
unsigned Length; // Number of memory locations in use
char * Mem; // Pointer to memory to hold characters
// Construct empty string
Mem = NULL;
Capacity = 0;
Length = 0;
Please help with comments, explanations, example code, or anything you think that would be helpful.
