c++ random number generator srandom code example

Example 1: c++ random

#include <cstdlib>
#include <iostream>
#include <ctime>
 
int main() 
{
    std::srand(std::time(nullptr)); // use current time as seed for random generator
    int random_variable = std::rand();
    std::cout << "Random value on [0 " << RAND_MAX << "]: " 
              << random_variable << '\n';
}

Example 2: random number cpp

// Add thus to with the headers
mt19937 rng(chrono::steady_clock::now().time_since_epoch().count());
// Generate a function that will give values between l and r inclusive
auto dist = uniform_int_distribution<int>(l, r);
// get the random number using dist(rng);
