Hi,
I am fairly new to C++ programming and I am trying to write a program
that will allow me to input the scores of a writing prompt given to my
students and output the percentage of students receiving the same
score. The scores are based on a rubric where the possible scores are
1, 2, or 3.
The code I am posting is just the input section. When I run the
program and input say, 16 scores of various 1s, 2s and 3s, the program
output says there were 16 score1s,
16 score2s and 16 score 3s. Could someone help me with this?
Thanks,
Ken

#include <iostream>
using std::cout;
using std::cin;
using std::endl;
#include <climits>

int main()
{
    int scoreCounter = 0; // number of grades entered
    int score1 = 0; // score values
    int score2 = 0;
    int score3 = 0;
    int result; // score entered by user
    
    while ( result != -1 ) { // loop until sentinel value read from
user

        cout << "Enter score, -1 to end: "; // prompt for input
        cin >> result; // read score from user

        if ( result = 1)
        score1 = score1 + 1; // add score to score1 total
        else
        if ( result = 2)
        score2 = score2 + 1; // add score to score2 total
        else
        if ( result = 3)
        score3 = score3 + 1; // add score to score3 total

        scoreCounter = scoreCounter + 1; // counts total number
of scores
     } // end while

     cout << "Total number of scores; " << scoreCounter << endl;
     cout << "Total number of score 1s: " <<score1 << endl;
     cout << "Total number of score 2s: " <<score2 << endl;
     cout << "Total number of score 3s: " <<score3 << endl;
     std::cin.ignore( INT_MAX, '/n');
     std::cin.get ();
     return 0;
}
