C++ random

To generate random numbers in C++, you can use the random library. Here are the steps to do so:

  1. Include the header file at the top of your C++ program. This header file contains the necessary functions and classes for generating random numbers.

  2. Create an instance of the random number generator. This can be done by declaring an object of the std::random_device class. For example:

std::random_device rd;

  1. Use the random number generator to seed a pseudo-random number generator. This is done by passing the random device object to the constructor of the std::mt19937 class. For example:

std::mt19937 gen(rd());

  1. Define a distribution for the random numbers you want to generate. This is done by declaring an object of the std::uniform_int_distribution class and specifying the range of values you want the random numbers to be generated within. For example, to generate random integers between 1 and 100:

std::uniform_int_distribution dist(1, 100);

  1. Use the distribution and the generator to generate random numbers. This can be done by calling the operator() function on the distribution object, passing the generator as an argument. For example:

int randomNum = dist(gen);

This will assign a random number between 1 and 100 to the variable randomNum.

  1. Repeat step 5 as many times as needed to generate multiple random numbers.

Remember to include the necessary header file, create an instance of the random number generator, define a distribution, and use the distribution and generator to generate random numbers.
