Determine what is printed by the following code.

18

Explanation:

a will get the values 3,6,9,12,15 and 18.

sum will get the values 0,3,9,18,30 and 45. When it gets to 45, the loop will not be executed anymore.

At that point, a is 18.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
