c++ - What kind of array declaration is this? -


after solving practice question,i red coder's solution.today saw array declaration have never seen before. declared array 

 char a['  '],b['  '];

please let me know ?

p.s- can duplicate question.i tried searching not find it(possibly because didn't know for),if duplicate please close question , give me link.

single quotes character constant.

  • ' ' space, 32 in ascii.
  • ' ' embedded tab character 9 in ascii
  • ' ' 2 spaces, implementation-defined int value.

in case, can supply expression integer type (or convertible one) inside [] of array declaration. end sizeof a being 32, or 9, or implementation-defined value.
