Generate Random Numbers in C++

#include <iostream>
#include <random>
#include <vector>

int main() {
    // Initialize random number generator
    std::random_device rd;  // Seed
    std::mt19937 gen(rd()); // Mersenne Twister engine
    std::uniform_int_distribution<> distrib(1, 100);

    // Generate a single random number between 1 and 100
    int randomNumber = distrib(gen);
    std::cout << randomNumber << std::endl;  // Example output: 42

    // Generate multiple random numbers
    std::vector<int> numbers;
    for (int i = 0; i < 10; ++i) {
        numbers.push_back(distrib(gen));

    }
