C++ generating random numbers

Question

My output is 20 random 1\'s, not between 10 and 1, can anyone explain why this is happening?

#include  
#include  
#include <         


        

Answer 1

It's much easier to use the library correctly than rand (assuming you're familiar enough with C++ that the syntax doesn't throw you).

#include 
#include 

int main() {
  std::random_device r;
  std::seed_seq seed{r(), r(), r(), r(), r(), r(), r(), r()};
  std::mt19937 eng(seed);

  std::uniform_int_distribution<> dist(1, 10);

  for(int i = 0; i < 20; ++i)
    std::cout << dist(eng) << " ";
}
