The Comparison Criterion
Explore the role of the comparison criterion in C++ ordered associative containers, focusing on using std::less and overloading operator<. Understand the concept of strict weak ordering and how it governs element sorting and equality checks for user-defined key types.

The default comparison criterion of the ordered associative containers is std::less. If you want to use a user-defined type as the key, you have to overload the operator <. It’s sufficient to overload the operator < for your data type because the C++ runtime compares, with ...
