Normal(Gaussian) Distribution Function in C++

Question

I need to know a way to have the Gaussian Distribution of 50 numbers. I know of the Boost library, which generates random numbers. In my case, I don\'t need random numbers; I ne

Answer 1

As of C++11 there is a normal (gaussian) distribution available in the standard library:

http://www.cplusplus.com/reference/random/normal_distribution/

The mean value and standard deviation are passed as arguments when creating it. The link above provides a good example:

// normal_distribution
#include 
#include 

int main()
{
  const int nrolls=10000;  // number of experiments
  const int nstars=100;    // maximum number of stars to distribute

  std::default_random_engine generator;
  std::normal_distribution distribution(5.0,2.0);

  int p[10]={};

  for (int i=0; i=0.0)&&(number<10.0)) ++p[int(number)];
  }

  std::cout << "normal_distribution (5.0,2.0):" << std::endl;

  for (int i=0; i<10; ++i) {
    std::cout << i << "-" << (i+1) << ": ";
    std::cout << std::string(p[i]*nstars/nrolls,'*') << std::endl;
  }

  return 0;
