I dont get this question

How many times will the following loop execute?

int i = 1; do { printf("looping"); } while ( i < 1 ) ;

Shouldn't the answer be zero since 1 is not smaller that 1 (i <1)

do while loops are guaranteed to run at least once. they run once, then they check the while condition. If its true, it loops again, if its false, it stops.

Look up the definition of "do while" and "while". They're a bit different from one another and you'll find your answer in that difference.
