Answer 1

//This program averages three test scores.
//It uses variable perfectScore as a flag.
#include <iostream>

using namespace std;    // It's using here

int main() {
    cout << "Enter your three test scores and I will"  // remove ; here
         << " average them: ";
    int score1, score2, score3; // use ; here
    cin >> score1 >> score2 >> score3;
    double average;
    average = (score1 + score2 + score3) / 3.0;
    bool perfectScore = false;  // declare perfectScore before using it here.
    if (average == 100)  //  remove ; here and use == for comparison
        perfectScore = true; // set the flag variable
    cout << "Your average is " << average << endl;
    if (perfectScore)
    {
        cout << "Congratulations!\n";
        cout << "That's a perfect score.\n";
    }
    return 0;   // return here at the end of main
}   // close using }
