While (57) printf("hello");

Question

in above statement in c find the result

Answer 1

infinite loop printing hello

Answer 2

Infinite. 0=False, but everything above 0 is not false. So because 57>0=True, the loop is while(True) and the True is never altered, so it's an infinite loop printing Hello to the screen.

Answer 3

In any case: while(a) where a!=0, an operation is infinitely execute... and this is why all embedded C programs consist of while(a); which is also known as superloop...
