partial_sum( ) creates a sequence that is a running total of the original sequence.

  
#include <iostream>
#include <vector>
#include <numeric>
using namespace std;
   
int main()
{
  vector<int> v(5), r(5);
  int i;
   
  for(i=0; i<5; i++) v[i] = i;

  for(i=0; i<5; i++)
    cout << v[i] << endl;
   
  partial_sum(v.begin(), v.end(), r.begin());
   
  for(i=0; i<5; i++)
    cout << r[i] << endl;
   
  return 0;
}
