b.    Initialize the array with the follows: “Mid1”, “Mid2”, “Final”, “total”.

c.     Declare an array of integers scores with 4 elements.

d.    Use the loop to read from the scores array the three scores and calculate total and put the result in the fourth array element.

e.    Declare an array of float percentage with 4 elements.

f.      Calculate the percentage of the score in each of element, assuming that the full mark is 60

g.    Print the three arrays.

 

The output should be as follows:-

 ---------------------------

Enter your score in Mid1: 20

Enter your score in Mid2: 15

Answer 1

#include <iostream>
#include <iomanip>

using namespace std;

int main ()
{
    float max = 60;
    string title[] = { "Mid1", "Mid2", "Final", "Total" };
    int score[4];
    score[3] = 0;
    for (int i = 0; i < 3; ++i)
    {
        cout << "Enter your score in " << title[i] << ": ";
        cin >> score[i];
        score[3] += score[i];
    }
    float percentage[] =
    {
    score[0] * 100 / max,
    score[1] * 100 / max,
    score[2] * 100 / max,
    score[3] * 100 / max
    };
    cout << "\r\n";
    for (int i = 0; i < 4; ++i)
    {
        cout << title[i] << " \t" << score[i] << " \t" << fixed << setprecision(1) << percentage[i] << "%\r\n";
    }
    return 0;
}
