std::experimental::randint: std::experimental::randint

NAME

std::experimental::randint - std::experimental::randint

Synopsis


Defined in header <experimental/random>
template <class IntType> (library fundamentals TS v2)
IntType randint(IntType a, IntType b);


Generates a random integer in the closed interval [a, b].

Parameters


a, b - integer values specifying the range

Return value


A random integer i in the closed interval [a, b], produced using a thread-local instance of std::uniform_int_distribution<IntType> invoked with the per-thread_random_number_engine.


Remarks


If IntType is not one of short, int, long, long long, unsigned short, unsigned int, unsigned long, or unsigned long long, the program is ill-formed.
The behavior is undefined if a > b.

Example


// Run this code


  #include <iostream>
  #include <experimental/random>


  int main()
  {
      int random_number = std::experimental::randint(100, 999);
      std::cout << "random 3-digit number: " << random_number << '\n';
  }

Possible output:


  random 3-digit number: 273
