How to generate random number between 1 to 10 in C++

The C++ generate random numbers within a specific range using the <random> header, which provides various classes and functions for random number generation. To generate a random number between 1 and 10, you can use the std::uniform_int_distribution class along with a random number generator engine, such as std::mt19937 (Mersenne Twister) or std::default_random_engine.

Here’s an example of how to generate a random number between 1 and 10:

C++
#include <iostream>
#include <random>

int main() {
    // Create a random number generator engine
    std::random_device rd;  // Seed from hardware entropy source (if available)
    std::mt19937 rng(rd()); // Mersenne Twister engine with rd as seed

    // Create a uniform distribution for integers in the range [1, 10]
    std::uniform_int_distribution<int> distribution(1, 10);

    // Generate a random number
    int random_number = distribution(rng);

    std::cout << "Random number between 1 and 10: " << random_number << std::endl;

    return 0;
}

In this example, std::random_device is used to obtain a random seed from the hardware entropy source (if available) to initialize the random number generator engine std::mt19937. The std::uniform_int_distribution is then used to specify the range [1, 10] for generating integers. Finally, distribution(rng) generates a random number between 1 and 10 using the specified engine and distribution.

Remember to include the <random> header to use the random number generation facilities. Keep in mind that the exact method and quality of random number generation might vary depending on the platform and C++ standard library implementation.
