The C++ Standard Template Library
Use and pitfalls of the C++ STL.
Summary
UseContainers
Use STL containers instead of self-made types. In particular, use std::vector instead of Sv*Arrays, std::list instead of DECLARE_LIST etc.
Use std::vector (or an appropriate string class) instead of C-arrays, if there is the slightest chance the array length may ever become variable.
In most cases vector is the best choice for a container.
You can use vector (and the c_str() function of string classes) to exchange data with non-C++ APIs.
UseAlgorithms
Prefer STL algorithm calls to handwritten loops.
Erase
Use the standard idiom to shrink the memory footprint of STL containers
PurePredicates
Make predicates pure functions, when used in STL algorithms.
