Question

array testgrades contains num_vals test grades read from input. organize the lines of code to create a for loop that sets sumextra to the total extra credit received. full credit is 100, so any grade over 100 has extra credit.
ex: if the input is 101 83 107 90, then the output is sumextra: 8, because 1+0+7+0 is 8.
note: not all lines of code on the left should be used in the final solution.

for (i = 0; i <= num_vals; ++i) {
for (i = 0; i < num_vals; ++i) {
if (testgradesi < 100) {
if (testgradesi > 100) {
}
}
sumextra = 0;
sumextra = sumextra + (testgradesi - 100);

main.cpp
#include <iostream>
using namespace std;
int main() {
const int num_vals = 4;
int testgradesnum_vals;
int i;
int sumextra;
for (i = 0; i < num_vals; ++i) {
cin >> testgradesi;
}

cout << \sumextra: \ << sumextra << endl;
return 0;
}

Explanation:

Step1: Initialize sumExtra to 0

sumExtra = 0;

Step2: Loop through all test grades

for (i = 0; i < NUM_VALS; ++i) {

Step3: Check if grade exceeds 100

if (testGrades[i] > 100) {

Step4: Add excess to sumExtra

sumExtra = sumExtra + (testGrades[i] - 100);

Step5: Close conditional and loop

  }
}

Step6: Output the final sumExtra

cout << "sumExtra: " << sumExtra << endl;

Answer:

The completed code snippet for main.cpp is:

#include <iostream>
using namespace std;

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

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

    for (i = 0; i < NUM_VALS; ++i) {
        if (testGrades[i] > 100) {
            sumExtra = sumExtra + (testGrades[i] - 100);
        }
    }

    cout << "sumExtra: " << sumExtra << endl;
    return 0;
}

For input 101 83 107 90, the output will be sumExtra: 8.
