2. A read() function
The read() function will allow the client programmer to specify the delimiting character (the character at which reading will stop). It should work just like the getline() function works for c-strings; that is, it should place everything up to but not including the delimiting character into the calling object, and it should also consume (and discard) the delimiting character. This will be a void function that will take two arguments, a stream and the delimiting character. It should not skip leading spaces. The limit of 127 characters imposed on the >> function above also applies to this function.
Hint: Don't try to read character by character in a loop. Use the in.getline() function to read the input into a non-dynamic array, then use strcpy() to copy it into your data member.
