C++ if...then statement
<p>So I'm trying to make a simple application that quizzes the user. It asks a question and the user answers 1, 2, 3, or 4. The app then takes that answer and if it is correct adds +1 to the total_score which will be displayed at the end. Everything looks sound to me, but when I run it and I get to the <code>if (q1_valid == false)</code> part it skips the cout and runs the goto no matter if q1_valid is true or false.</p>

<pre><code>#include &lt;iostream&gt;

using namespace std;

int main()
{
    int q1_answer;
    int total_score;
    bool q1_correct;
    bool q1_valid;

    Question_1:
    cout &lt;&lt; "Question 1 (#3 is correct)" &lt;&lt; endl;
    cout &lt;&lt; "1.) Answer 1" &lt;&lt;endl;
    cout &lt;&lt; "2.) Answer 2" &lt;&lt;endl;
    cout &lt;&lt; "3.) Answer 3" &lt;&lt;endl;
    cout &lt;&lt; "4.) Answer 4" &lt;&lt;endl;
    cin &gt;&gt; q1_answer;

    if (q1_answer == 1)
    q1_correct = false;
    q1_valid = true;

    if (q1_answer == 2)
    q1_correct = false;
    q1_valid = true;

    if (q1_answer == 3)
    q1_correct = true;
    q1_valid = true;

    if (q1_answer == 4)
    q1_correct = false;
    q1_valid = true;

    if (q1_valid == false)
    cout &lt;&lt; "Invalid answer." &lt;&lt;endl;
    goto Question_1;

    if (q1_correct == true)
    cout &lt;&lt; "Correct!" &lt;&lt;endl;
    (total_score + 1);
    goto Question_2;

    if (q1_correct == false)
    cout &lt;&lt; "Incorrect." &lt;&lt;endl;
    goto Question_2;

    if (q1_valid == false)
    goto Question_1;

    Question_2:
    cout&lt;&lt; "Q2" &lt;&lt;endl;
cin.ignore();
cin.ignore();
}
