With the help of the seed value, srand() sets the stage for the generation of pseudo-random numbers by the rand() function. This function requires a seed value which forms the basis of computation of random numbers. The srand() function in C++ can perform pseudo-random number calculation. So even though an output number produced may seem random, the values are mathematically computed. The idea behind pseudo-random numbers is that a computer does not have a thinking process to select a random number. In the world of computers, random numbers form an essential component to add the flavor of anonymity and security.Ī random number generator forms the backbone of creating pseudo-random numbers. In this article, we’ll go over the functions needed to create a random number generator in C++.
