Expert Solution
Step 1

// C++  Program

#include <iostream>

using namespace std;

int main()
{
    // define array
    int nums[] = {124, 678, -127, 12, 0, 78, -999, 919, 45, -10};
    
    // define sum
    int sum = 0;
    
    // loop through nums
    for (int i = 0; i < 10; i++) {
        // check if it's a positive integer and three digits
        if (nums[i] >= 100 && nums[i] <= 999) {
            // add to sum
            sum += nums[i];
        }
    }
    
    // print sum
    cout << sum << endl;
    
    return 0;
}
