Question

What is linear_congruential_engine?

(a) Pseudo-random number engine that generates random unsigned integers in the range [0, 2^w-1] for some w using Mersenne Twister algorithm

(b) Pseudo-random number engine that generates random unsigned integers

(c) Pseudo-random number engine that generates random unsigned integers in the range [0, 2^w-1] for some w using lagged Fibonacci generator

(d) Pseudo-random number engine that generates random signed integers in the range [0, 2^w-1] for some w using Mersenne Twister algorithm

I had been asked this question by my college professor while I was bunking the class.

This interesting question is from Generators topic in portion Class Hierarchies, Library & Containers of C++

Answer 1

Correct answer is (b) Pseudo-random number engine that generates random unsigned integers

For explanation: linear_congruential_engine is a simple Pseudo-random number engine that generates random unsigned integer using the basic algorithm.
