Multimap operators

Syntax:

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

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

Two multimaps are equal if:

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

Comparisons among multimaps are done lexicographically.
