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
