0 and RAND_MAX. On transformer, RAND_MAX is 2147483647. What is a pseudo-random number? It is a number that is not truly random, but appears random. That is, every number between 0 and RAND_MAX has an equal chance (or probability) of being chosen each time rand() is called. (In reality, this is not the case, but it is close).
