Yesterday's programming program was dead, and there was a dead cycle when traced. It's really thinking that it is a ghost, don't believe it, look, it is the following: main () {int loop = 1; while (loop <5) {Int Arr [1000]; for (int i = 0; i <= 1000; i ) {Arr [i] = 1;} loop ;}} Everyone thinks first, waiting for the answer, the stack, the array is a bit good, so I will share it.
