experimental::randint
Defined in header
<experimental/random>
template< class IntType >
IntType randint( IntType a, IntType b );
(library fundamentals TS v2)
IntType randint( IntType a, IntType b );
Generates a random integer in the closed interval [a, b].
[edit] Parameters
a, b
-
integer values specifying the range
[edit] 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.
[edit] 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.
[edit] Example
Run this code
#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
