c++ random

To generate random numbers in C++, you can make use of the <random> library. Here are the steps to generate random numbers in C++:

  1. Include the <random> library:
#include <random>
  1. Create a random number generator engine:
std::random_device rd;
std::mt19937 gen(rd());

In this step, we use std::random_device to obtain a random seed for the generator engine. Then, we use std::mt19937 as the generator engine, which is a widely used and well-tested random number generator.

  1. Define the distribution range:
std::uniform_int_distribution<> dis(min, max);

Here, min and max represent the minimum and maximum values for the desired range of random numbers. The std::uniform_int_distribution is used to define a uniform distribution of integers within the specified range.

  1. Generate random numbers:
int randomNum = dis(gen);

This line generates a random number within the defined range using the generator engine gen and the distribution dis. The generated random number is then assigned to the variable randomNum.

You can repeat step 4 to generate multiple random numbers as needed.

Remember to include the necessary headers and use the appropriate namespaces in your code.
