int x = 2;char * str = "ABCD"; int y = (X-strlen (str))/3;printf ("%d\n", y);　　Here the strlen () return value is unsigned, and the (X-strlen (str)) is coerced to an unsigned number, i.e. the complement of 2 is divided by 3 and the result is 14316557

c++11 tuple tuplesA tuple container (tuple), which is a tuple container that is not contained in any structure, is fast and low quality (shoddy, quick and dirty), which can be used to return multiple return values to a function;The tuple container,
