MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Answer: a Explanation: The DDA algorithm takes more time than other algorithm.

Detailed explanation-2: -Explanation: The only drawback of DDA algorithm was that it produces floating point results which increases the overall complexity. This algorithm is used for calculating intermediate coordinate points between the given source and ending points by only using integer addition and subtraction.

Detailed explanation-3: -Disadvantage: It involves floating point additions rounding off is done. Accumulations of round off error cause accumulation of error. Rounding off operations and floating point operations consumes a lot of time.

Detailed explanation-4: -Advantage: It is the most straightforward algorithm. It is a faster process for calculating pixel positions. Disadvantage: Floating-point arithmetic in DDA technique is time-consuming. Endpoint accuracy is poor.

Detailed explanation-5: -Answer: c Explanation: DDA stands for digital differential analyzer.
