Ep 483: Stop Using rand, Start Using Random

Summary

This episode provides a practical introduction to the C++ header, which offers superior random number generation compared to the old C rand() function. Jason demonstrates using std::random_device for non-deterministic random values, std::mt19937 (Mersenne Twister) for reproducible pseudorandom sequences with seeds, and various distributions like uniform_int_distribution. The video shows how to combine engines with distributions to generate random numbers in specific ranges and patterns with proper statistical properties.
