Summary

Prefer STL Containers (Cont)

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.

Erasing Container Memory (EraseMem)

Use the standard idiom to shrink the memory footprint of STL containers.

Details

Pure Predicates (PurePred)

Make predicates pure functions, when used in STL algorithms.
