MyString object will have the ability to make a full deep$-$copy of itself when copied of the assignment, but full documentation will be required for the next part. Here is a list of the operations this class must support:

A length member function that returns the number of characters in the string. Use strlen$().$basis. Use strcpy$().$ Printing a MyString to a stream using an overloaded insertion$)$ operator, which should simply print out its characters. Use $$ of the comparison operator. You must do this using only one function for each of the six operators. Don't forget to include the big$-3.$ may NOT use anything from the C$++$ string class!!
