or the lines of code to create two for loops that print all elements in coursegrades, following each element with a space including the last. print forwards, then backwards. after each loop, print a newline.
ex: if the input is 7 9 11 10, then the output is:
7 9 11 10
10 11 9 7

main.cpp
load default template...
#include <iostream>
using namespace std;
int main() {
const int num_vals = 4;
int coursegradesnum_vals;
int i;

for (i = 0; i < num_vals; ++i) {
cin >> coursegradesi;
}

return 0;
}

Explanation:

Step1: Add forward loop

for (i = 0; i < NUM_VALS; ++i) {
    cout << courseGrades[i] << " ";
}
cout << endl;

Step2: Add backward loop

for (i = NUM_VALS - 1; i >= 0; --i) {
    cout << courseGrades[i] << " ";
}
cout << endl;

Answer:

The completed main.cpp code is:

#include <iostream>
using namespace std;

int main() {
    const int NUM_VALS = 4;
    int courseGrades[NUM_VALS];
    int i;

    for (i = 0; i < NUM_VALS; ++i) {
        cin >> courseGrades[i];
    }

    // Forward print loop
    for (i = 0; i < NUM_VALS; ++i) {
        cout << courseGrades[i] << " ";
    }
    cout << endl;

    // Backward print loop
    for (i = NUM_VALS - 1; i >= 0; --i) {
        cout << courseGrades[i] << " ";
    }
    cout << endl;

    return 0;
}

When given input 7 9 11 10, the output will be:

7 9 11 10
10 11 9 7
