Actually, although I didn'tshow it in the example but I defined the
variable "word" at the beginning of the class as:
private:
char *word;
As a pointer.
Thus, when the allocated memory is killed can'tit be done as :
delete word;
Or is it still required that it be done in array format as:
delete[] word; ???
