I really don't like the rand() function.I wanted to use the library but I don't really know how to set up a range for example from 1 to 3. I want to "random" these numbers(1,2,3) and not huge numbers like 243245.This code is how you can use the random library and print random numbers
#include <iostream>
#include <string>
#include <random>
using namespace std;
int main()
{
minstd_rand simple_rand;
simple_rand.seed(NULL);
for (int ii = 0; ii < 10; ++ii)
{
std::cout << simple_rand() << '\n';
}
}
#include <iostream>
#include <random>
int main()
{
std::random_device rd; //Will be used to obtain a seed for the random number engine
std::mt19937 gen(rd()); //Standard mersenne_twister_engine seeded with rd()
std::uniform_int_distribution<> dis(1, 3);
for (int n=0; n<10; ++n)
//Use dis to transform the random unsigned int generated by gen into an int in [1, 6]
std::cout << dis(gen) << ' ';
std::cout << '\n';
}
