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;
