Make Simple Tasks Simple
In the slide deck that Bjarne Stroustrup presented for his “Make Simple Tasks Simple” CppCon keynote speech, he walked through a progression of refactorings that reduced an (arguably) difficult-to-read, multi-line, C++98 code segment (that searches a container for an element matching a specific pattern) into an expressive, C++11 one liner:
Some people may think the time spent refactoring the original code was a pre-mature optimization and, thus, a waste of time. But that wasn’t the point. The intent of the example was to illustrate several features of C++11 that were specifically added to the language to allow sufficiently proficient programmers to “make simple tasks simple (to program)“.
Note: After the fact, I discovered that “MemVec” should be replaced everywhere with “v” (or vice versa), but I was too lazy to fix the pic :). Can you find any other bugs in the code?
