Answer 1

Cnange这句话

   int findlowest(num1, num2, num3, num4, num5);

到

   int lowest = findLowest(num1, num2, num3, num4, num5);

或仅仅作为

   findLowest(num1, num2, num3, num4, num5);

因为您没有使用返回值。

此功能的名称为findLowest。

这部分代码

cout << "Are there any more test scores?" << endl;
cin >> response;
cout << endl;
if (response == "yes")
{
    getScore(num1, num2, num3, num4, num5);
    //calcAverage(num1, num2, num3, num4, num5);
}

没有任何意义。

函数findLowest也错了。它找不到最低价。例如，考虑num1，num2，num3，num4，num5相应地具有平衡5,4,3,2,1的情况。

甚至函数calcAverage都是错误的，因为它使用未初始化的变量最低。

应该有

int lowest = findLowest(num1, num2, num3, num4, num5);

然而由于函数findLowest的设计不好，关于最小数字的消息将被输出两次。

Answer 2

另请注意，您将函数定义为 int findLowest（int，int，int，int，int）; 与＆＃34; L＆＃34; 你打电话给它 int findlowest（num1，num2，num3，num4，num5）; 用＆＃34; l＆＃34; 功能名称不一样:)。
