Submitter's editorialized title mischaracterizes the OP > All the tasks focused on iteration on a collection using a C++ vector object. That's comparing "functional style" collections to iteration. It is readily apparent that C++ syntax is so troublesome that "functional collections" won't be a win for small iteration blocks. We had the same debate for functional Java collection methods (although the Java 8 lambdas tilt it more closely in functional Java's favor) The main use case for C++ lambdas is for declaring callbacks.
