whitespace - Is there a reference for what the white space character symbols represent in eclipse? -


i'm doing text compare unit test in eclipse, , difference in whitespace, i've got 'show white space characters' on.

enter image description here

question - there reference characters represent?

i know >> symbol tab ("\t"), , imagine pi looking symbol new line ("\n").

  • u+0020 - • - space
  • u+3000 - ˚ - ideographic space
  • u+0009 - » - \t - tab
  • u+000d - ¤ - \r - carriage return
  • u+000a - ¶ - \n - line feed

if want show/hide them on eclipse

  1. go preferences -> general -> editors -> text editors

c++ - Why doesn't unordered_set provide an array access operator -

i'm curious why stl container unordered_set , has constant time complexity random access on average, not provide method accessing elements distance first element in container. example: t& unordered_set::operator[](size_t index) { return *(begin() + index); } accessing element "by distance" implies there meaningful way measure distance. trouble std::unordered_set is is, well, unordered . hence, there no meaningful way of explaining "some distance beginning" in non-arbitrary way. if want access distance, copy data vector: std::vector tmp(unordered.begin(), unordered.end());
