std::generate_n is an algorithm to generate a sequence of different elements.


#include <algorithm>

#include <iostream>

#include <iterator>

#include <vector>



int main()

{

  //Create std::vector<int> v of size 10 filled with zeroes

  const std::size_t sz = 10;

  std::vector<int> v(sz,0);

  //Fill v with random numbers

  std::generate_n(v.begin(),sz,std::rand);

  //Display v (using CoutContainer code snippet)

  std::copy(v.begin(),v.end(),std::ostream_iterator<int>(std::cout,"\n"));

}
