Question

Write a program that prompts the user to enter five test scores and then print the average test score to the screen. (Assume that the test scores are decimal numbers). Use the following 5 numbers:     10.5      5.5        20.0      10.0      5.5.

I am having trouble understanding where the 5 values are entered in the program.

The program has been provided:

#include <iostream>
    #include <iomanip>
   
    using namespace std;
    
    int main()
    {
        double testScore1;
        double testScore2;
        double testScore3;
        double testScore4;
        double testScore5;
   
        cout << "Enter test score 1: ";
        cin >> testScore1;
        cout << endl;
   
        cout << "Enter test score 2: ";
        cin >> testScore2;
        cout << endl;
       
        cout << "Enter test score 3: ";
        cin >> testScore3;
        cout << endl;
       
        cout << "Enter test score 4: ";
        cin >> testScore4;
        cout << endl;
       
        cout << "Enter test score 5: ";
        cin >> testScore5;
        cout << endl;
       
        cout << "Average test score: " << (testScore1+testScore2+testScore3+testScore4+testScore5)/5 << endl;
        cout << endl;
   

        // when using Visual Studio, use the system/pause command to display the results of your program
        // system("pause");

        return 0;
    }

Program :

#include <iostream>
#include <iomanip>

using namespace std;
  
int main()
{
double testScore1; // Variable declaration for first score
double testScore2; // Variable declaration for second score
double testScore3; // Variable declaration for third score
double testScore4; // Variable declaration for fourth score
double testScore5; // Variable declaration for fifth score
cout << "Enter test score 1: ";
cin >> testScore1; // Accept the first score
cout << endl;

cout << "Enter test score 2: ";
cin >> testScore2; // Accept the second score
cout << endl;

cout << "Enter test score 3: ";
cin >> testScore3; // Accept the third score
cout << endl;

cout << "Enter test score 4: ";
cin >> testScore4; // Accept the fourth score
cout << endl;

cout << "Enter test score 5: ";
cin >> testScore5; // Accept the fifth score
cout << endl;

cout << "Average test score: " << (testScore1+testScore2+testScore3+testScore4+testScore5)/5 << endl; // Find the average of score and print the score
cout << endl;
return 0;
}

Output :
