c++ - Most elegant looping construct? -

-

sorry newb question. i'm still learning programming. i'm using c++, , need this:

int n; {     n = get_data();     if(n != -1)         send(n); } while(n != -1);

this sketch. anyway doesn't feel real elegant. have have test twice. test once , set flag, doesn't feel real elegant either since have check flag twice. seems there should way more easily, since it's easy want do.

int n; while (-1 != (n = get_data())) {     send(n); } // while
