template< class IntType >
IntType randint( IntType a, IntType b );
Generates a random integer in the closed interval [a, b].
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.
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.
[edit] Example#include <experimental/random>
#include <iostream>
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[edit] See also reseeds the per-thread random engine
