Returns a negative number, zero, or a positive number when x is logically 'less than', 'equal to', or 'greater than' y. With this method, we will compare two strings by using the comparison operator ==. This value is less than 0 if the first string is less than the second string, greater than 0 if the first string is greater than the second string or 0 if both strings are equal. Returns a negative number, zero, or a positive number when x is logically 'less than', 'equal to', or 'greater than' y. We will write different C++ programs to compare two strings.
