Error message still printing even though exit condition met and entered

Question

I'm having quite the issue trying to figure out why these code segments are printing the error message even when I have done cout statements within the block that should return true / not print that error message. Any ideas? I'm new here so please let me know if this isn't allowed. Thanks!

Use of function:

case 'a':
        {
            // Format: a ID credits GPA
            // Adds a student with the given student ID (ID), number of 
            // credits (credits), and overall GPA (GPA) to the database. 
            // If the student is already in the database, an error 
            // message should be printed indicating this.

            int credits = 0;
            double gpa = 0;
            cin >> studentID;
            cin >> credits;  
            cin >> gpa;

            // Adds the student and checks to see if the student was actually added
            // or if there was an existing student with the specified ID

            bool added = addStudent(studentID, credits, gpa);
            if(added == false);
            {
                cout << "Student already exists in database, nothing changed." << endl;
                // Still prints this when executed with valid 
            }
            break;
        }

Function for adding student to array:

bool addStudent (int id, int numCredits, double gpa) {

// Check to see if student exists

if (nextEntry != 0)
{
    for (int x = 0; x < 7000; x++) {
        Student tmp = studentRecords[x];
        if (tmp.studentId == id)
        {
            return false;
            cout << "hey" << endl;
        }
    }
}

// If student does not exist, add to records database
if (nextEntry != 7000)
{
    studentRecords[nextEntry].studentId = id;
    studentRecords[nextEntry].numCredits = numCredits;
    studentRecords[nextEntry].gpa = gpa;
    nextEntry++;
    return true;
    // confirmed I can get here
}

return false;
}

Answer 1

You have an extra ; after your if (added==false) statement. This will terminate the if statement and the code after will run regardless of the check.
