217 PointsQuestion on "do" loop
int i = 1; do { printf("looping %d", i); } while ( i < 1 );
Why wouldn't it loop through zero times, since i is set to 1 (it's not less than 1)?

Thus even if it starts off with the right condition to terminate, a single round of execution would still go before any test for termination. This is in contrast with the while(...){ ... } syntax, which performs the test before each loop.
