Answer 1

Answer:

The correct code is :

# include <iostream>
using namespace std;

int main()
{
      cout << "Enter your 3 test scores and I will average them:";
     int score1, score2, score3;
     bool perfectScore=false;
     cin >> score1 >> score2 >> score3;
     int average;
     average = (score1 + score2 + score3) / 3;
     if (average== 100)
        perfectScore = true; // Set the flag variable
    cout << "Your average is " << average<< endl;
   
     if (perfectScore)
     {
         cout << "Congratulations!\n";
         cout << "That's a perfect score.\n";
         cout << "You deserve a pat on the back!\n";
     }
return 0;
}

Explanation:

there has to be semicolon after declaring score1,score2,score3; and 8 and 9 has to be in a single line.we should convert average variable to int because we are comparing with 100. and we should remove semi colon after if conditions.We should declare all the variables before we are using them. If we do not assign any value to them,randomly they will take any value as a default value.so by default perfect score variable is false.
