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 behavior is undefined if a > b.
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:
