Incrementing iterators: ++it more efficient than it++? [duplicate]

http://stackoverflow.com/questions/1077026/incrementing-iterators-it-more-efficient-than-it

share improve this question The reason behind the preincrement being faster is that post increment has to make a copy of the.. form of postincrement which shows that it has to do preincrement plus some more work T T operator int T old this remember our.. value this always implement postincrement in terms of preincrement return old return our original value As others have noted it's..
