One line or the other is not correct. The size of an array must be a constant, and you can't read into a const. If you want to do something like this, use malloc:
cin >> x; int *a = (int *)malloc(x*sizeof(int)); You can now use "a" as if it is an array of size x. Be sure to free the memory before "a" goes out of scope.
