Example

In below example explains about std::greater.

#include <iostream>
#include <functional>
#include <algorithm>

int main () {
   int numbers[]={200,40,50,100,30};
   std::sort (numbers, numbers+5, std::greater<int>());
   for (int i=0; i<5; i++)
      std::cout << numbers[i] << ' ';
   std::cout << '\n';
   return 0;
}

Let us compile and run the above program, this will produce the following result −

200 100 50 40 30
