如果无效函数内的循环不起作用

if loop inside a void function not working

所以我正在为 class 编写一个程序,并且我在函数定义内设置了一个 if 循环来为条目设置参数。我应该只接受 0 到 10 之间的输入。但是它只捕获小于0的数字。它不会捕获大于10的数字。

int main()
{
    float score1, score2, score3, score4, score5;
    cout << endl;
    cout << "Judge #1: " << endl;
    getJudgeData(score1);
    cout << "Judge #2: " << endl;
    getJudgeData(score2);
    cout << "Judge #3: " << endl;
    getJudgeData(score3);
    cout << "Score #4: " << endl;
    getJudgeData(score4);
    cout << "Score #5:  " << endl;
    getJudgeData(score5);

    calcScore(score1, score2, score3, score4, score5);

    return 0;
}

void getJudgeData (float &score)
{
    cin >> score;

    if(score < 0 || score > 10)
    {
        cout << "Error: Please enter a score between 0 and 10." << endl;
        cin >> score;
    }
}

请将 getJudgeData 函数中的 if 条件更改为 while 循环:

void getJudgeData (float &score)
{
    cin >> score;

    while (score < 0 || score > 10)
    {
        cout << "Error: Please enter a score between 0 and 10." << endl;
        cin >> score;
    }
}

否则只检查一次条件,即每次判断的第一次输入。如果我没有正确理解您的问题,这不是故意的。
