Raise all values in a vector by a given percentage

  

#include <iostream>

#include <vector>



using namespace std;



void raise_by_percent(vector<double>& v, double p)

{  

   for (int i = 0; i < v.size(); i++)

      v[i] = v[i] * (1 + p / 100);

}



int main()

{  

   vector<double> salaries(5);

   salaries[0] = 3.0;

   salaries[1] = 6.0;

   salaries[2] = 4.0;

   salaries[3] = 7.0;

   salaries[4] = 5.0;



   raise_by_percent(salaries, 4.5);



   for (int i = 0; i < salaries.size(); i++)

      cout << salaries[i] << "\n";



   return 0;

}
