Container operators

C/C++ Reference

Container operators
Syntax:
  #include <set>
  container operator=(const container& c2);
  bool operator==(const container& c1, const container& c2);
  bool operator!=(const container& c1, const container& c2);
  bool operator<(const container& c1, const container& c2);
  bool operator>(const container& c1, const container& c2);
  bool operator<=(const container& c1, const container& c2);
  bool operator>=(const container& c1, const container& c2);

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

Two multisets are equal if:

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

Comparisons among multisets are done lexicographically.
