1. The TimeType class supplies two member functions, Equal and LessThan, that correspond to the relational operators == and <. Show how client code can simulate the other four relational operators (!=, <=, >, and >=) using only the Equal and LessThan functions. Specifically, express each of the following pseudocode statements in C++, where time1 and time2 are objects of type TimeType. |
