Answer

Explanation:

Step1: Missing semicolon after variable declaration

The line int score1, score2, score3, should be int score1, score2, score3;

Step2: Incorrect assignment operator in 'if' condition

The line if (average = 100); should use the equality - comparison operator == instead of the assignment operator =, so it should be if (average == 100);

Step3: Using variable before initialization

The variable perfectScore is used in the line perfectScore = true; before it is declared. It should be declared before this assignment.

Step4: Unnecessary semicolon after 'if' condition

The line if (perfectScore); has an unnecessary semicolon which will cause the block following it to not be part of the if - statement. It should be if (perfectScore) without the semicolon.

Step5: Return statement in wrong scope

The return 0; statement is inside the if - block for perfectScore. It should be at the end of the main function, outside of this if - block.

Answer:

  1. Missing semicolon after int score1, score2, score3,.
  2. Incorrect assignment operator in if (average = 100);.
  3. Using perfectScore before declaration.
  4. Unnecessary semicolon after if (perfectScore);.
  5. return 0; in wrong scope.
