## List operators

Syntax:

        #include <list>
        list& operator=(const list& c2);
        bool operator==(const list& c1, const list& c2);
        bool operator!=(const list& c1, const list& c2);
        bool operator<(const list& c1, const list& c2);
        bool operator>(const list& c1, const list& c2);
        bool operator<=(const list& c1, const list& c2);
        bool operator>=(const list& c1, const list& c2);

All of the C++ containers can be compared and assigned with the standard comparison operators: ==, !=, <=, >=, <, >, and =. Performing a comparison or assigning one list to another takes linear time.

Two lists are equal if:

1. Their size is the same, and
2. Each member in location i in one list is equal to the the member in location i in the other list.

Comparisons among lists are done lexicographically.
