Which of the following statements is true?
a)int expressions are always computed exactly; but float expressionscan suffer round-off error
b)float expressions are always computed exactly; but int expressionscan suffer round-off error
c)both int and float expressions can suffer round-offerror
d)both int and float expressions will always be computedexactly

Option (A) int expressions are always computed exactly; but float expressions can suffer round-off error.

Explanation:

Round - Off Error can be defined as the digital computers have limitations on denoting the decimal numbers,  due to this the floating point numbers have to be rounded off or even it is represented exactly after the calculation on the numbers the resulting number has to be adjusted / rounded off according to the specified precision. The resulted number has to be rounded off back to the required precision, this leads to the round off errors in digital computers. As integers don't need to go through the rounding off in computers, the integer numbers don't have round off errors, only floating point numbers have round off errors. So, options (B) , (C) and (D) are false.

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?
