C ++ getline錯誤

Question

我收到此錯誤，但無法解決：

沒有重載函數“ getline”的實例與參數列表匹配的參數類型為：（std :: istream，MyEnum）

碼

enum MyEnum // Needs to be before the struct that uses it
{
    Dog, Cat, Fish, Squirrel
};
struct MyStruct
{
    int a;
    float b;
    string c;
    MyEnum d;
};
int main()
{
    char myCString[arraySize] = { 0 };
    char myOtherCString[] = { "Yet another string" };
    int myInt[4] = { 27, 39, 0, 42 };
    string myString;
    MyStruct aStruct = { 4, 3.5, "Dogs", Dog };
    int x;
    int * pX = &x;
    array <MyStruct, arraySize> Animals;
    // Storing values in uninitialized variables
    myCString[0] = 'A';
    myString = "A third string";
    x = 4;
    for (int i = 0; i < arraySize; i++)
    {
        Animals[i].a = rand() % 10;
        Animals[i].b = rand() % 100 / 100.0;
        Animals[i].c = MyEnum(rand() % 4);
        cout << "Enter a name: ";
        getline(cin, Animals[i].d);
    }

Answer 1

您可能想在Animals[i].c獲得輸入，因為c是string ，而d不是。

另外，您可能想要分配MyEnum(rand() % 4); 對Animals[i].d

for (int i = 0; i < arraySize; i++)
{
    Animals[i].a = rand() % 10;
    Animals[i].b = rand() % 100 / 100.0;
    Animals[i].c = MyEnum(rand() % 4);
    //        ^^^
    // Change it to Animals[i].d
    cout << "Enter a name: ";
    getline(cin, Animals[i].d);
    //                     ^^^
    // Change it to Animals[i].c
}

這只是一種不良的命名方式，您應該為變量使用一些有意義的名稱，而對於某些有意義的名稱，您可能永遠不會出現這種錯誤。
