C++11: How to set seed using . I am exercising the random library, new to C++11. I wrote the following minimal program: #include #include using namespace std; int main () { default_random_engine eng; uniform_real_distribution urd (0, 1); cout << "Uniform [0, 1): " << urd (eng); } WebMar 30, 2024 · std::mt19937 (since C++11) class is a very efficient pseudo-random number generator and is defined in a random header file. It produces 32-bit pseudo-random numbers using the well-known and popular algorithm named Mersenne twister algorithm. std::mt19937 class is basically a type of std::mersenne_twister_engine class.
