Arrayのサイズ非指定

Arrayのサイズ非指定

sample.c

int main() {
  int a[] = { 1, 2, 3 };  

  char c = 'x';
  char *cptr = "xyz";       //equivalent to array[4] = {'x','y','z','\0'}

  char carr1[] = {'a','b'};
  char carr2[] = "text";    //equivalent to array[5] = {'t','e','x','t','\0'}
  char *captr[] = {"p","q"};//equivalent to *array[2] = {*{'p','\0'}, *{'q','\0'}}
}

まとめ

記号	役割	区切り
{}	xxx(要素に準拠)[]	カンマ区切り
""	char[]	文字区切り
''	char	-
