string compares can costly. there's statistic floating around says high percent of string compares can eliminated first comparing string sizes. i'm curious know whether nsstring compare: method takes consideration. know? according sources here (which 1 implementation, others may act differently), compare doesn't check length first, makes sense since it's not equality check. returns less-than/equal-to/greater-than return code, has check characters, if lengths same. a pure isequal -type method may able shortcut character checks if lengths different, compare not have luxury. it checks of length against zero, not comparisons of 2 lengths against each other.

this question has answer here: when function has specific-size array parameter, why replaced pointer? 3 answers let me ask question test program: #include <iostream> void testsizeof(char* buf, int expected) { std::cout << "buf sizeof " << sizeof(buf) << " expected " << expected << std::endl; } int main () { char buf[80]; testsizeof(buf, sizeof(buf)); return 0; } output: buf sizeof 8 expected 80 why receve 8 instead of 80 ? upd found similar question when function has specific-size array parameter, why replaced pointer? you're taking size of char* , not of array of 80 characters. once it's decayed pointer, it's no longer seen array of 80 characters in testsizeof. it's seen normal char* . as possible reason why, consider code: char* ch = new char[42]; ...
