.. title:: clang-tidy - cert-msc50-cpp cert-msc50-cpp ============== Pseudorandom number generators use mathematical algorithms to produce a sequence of numbers with good statistical properties, but the numbers produced are not genuinely random. The ``std::rand()`` function takes a seed (number), runs a mathematical operation on it and returns the result. By manipulating the seed the result can be predictable. This check warns for the usage of ``std::rand()``.
