Some time ago I've seen an inspiring talk from CppCon 2013: "C++ Seasoning" by Sean Parent. One of the main points of this presentation was not to use raw loops. Instead, prefer to use existing algorithms or write functions that 'wraps' such loops. I was curious about this idea and searched for nice code examples. Here is my short list of usage of algorithms from the C++ std library that might help in writing better code.
Of course. I could not skip two prominent examples from the original "C++ Seasoning" talk: slide and gather.
