public static member function
<random>

std::linear_congruential_engine::max

static constexpr result_type max();
Maximum value
Returns the maximum value potentially returned by member operator(), which for linear_congruential_engine is modulus-1 (where modulus is a member constant, alias of the fourth template parameter, m).

Parameters

none

Return value

modulus-1
result_type is a member type, defined as an alias of the first class template parameter (UIntType).

// linear_congruential_engine::min and max
#include <iostream>
#include <chrono>
#include <random>

int main ()
{
  unsigned seed = std::chrono::system_clock::now().time_since_epoch().count();
  std::minstd_rand0 generator (seed); // minstd_rand0 is a standard linear_congruential_engine

  std::cout << generator() << " is a random number between ";
  std::cout << generator.min() << " and " << generator.max();

  return 0;
}

Possible output:
204181028 is a random number between 1 and 2147483646


Complexity

None (compile-time constant).
