Question

any can help me for this code, am trying to calculate each student score , total average and grade using vector. but it prints wrong for the last student score and total average. it addes extra in put for the last student. i don't know why. it suppose print 74.2 average but it print out 72.2

here is the input given

Oneill 59 67 56 70 97
Hess 91 50 85 62 63
Ritter 81 67 99 62 97
Munoz 52 68 55 52 94
Bright 87 97 89 78 100
Pennington 56 67 86 65 82
Dawson 98 91 78 58 56
Ashley 54 60 72 75 89
Todd 87 51 81 68 51
Swanson 98 69 90 92 56

and here is my code what i try

#include <iostream>
#include <string>

#include <iomanip>

#define NUM_SCORES 5

   int total = 0;
   for (int i = 0; i < NUM_SCORES; i++)
   {
       total += scores[i];
   }
   return total;
}

//get average
