字符串类型向量 C++

Question

在我下面分享的代码中，我想在AddStoreCustomer()部分中使用 output 向量数据类型。 这就是代码的工作方式。 但是代码中有一个错误。 如果我在客户变量中输入一个单词，代码就可以正常工作。 但是当我在这个变量中输入两个单词并且它们之间有一个空格时，代码不起作用。

        #include <vector>

Answer 1

发生这种情况是因为您正在使用cin>>读取输入，该输入一直读取到第一个空白符号。 如果您想阅读整行，请考虑使用std::getline()代替：

getline(cin, customer);

Answer 2

谢谢您的帮助。 我修改了如下代码。 但是，当我运行代码时，它直接输出而不要求我输入。 我想知道我是否以错误的方式使用getline()将其更新为getline(cin,customer)而不是cin>> customer

void AddStoreCustomer() {
    int id, found, menu;
    string customer;
    cout << "Lutfen Musteri Eklemek Istediginiz Magazanin ID Numarasini Girin:";
    cin >> id;
    found = Search2(id);
    if (found == -1)
    {
        cout << "Magaza Bulunamadi" << endl;
    }
    else {
        cout << "Magaza Bulundu.\n" << "Lutfen Magaza Veri Tabanina Eklemek Istediginiz Musterinin Bilgilerini Girin: ";
        //cin >> customer;
        getline(cin, customer);
        s2[found].setStoreCustomer(customer);
        cout << "Girilen Musteri Bilgisi Secilen Magazaya Eklendi";
        cout << "Magaza ID: " << s2[found].getStoreID() << "\n Magaza Adi: " << s2[found].getStoreName() << "\n Magazanin Bulundugu Il: " << s2[found].getStoreCity() << "\n Magazanin Bulundugu Ilce:" << s2[found].getStoreTown() << "\n Magaza Iletisim Numarasi: " << s2[found].getStoreTel() << endl;
        cout << "Musteriler: " << endl;
        for (int i = 0; i < s2[found].getStoreCustomer().size(); i++)
        {
            cout << "\t\t" << s2[found].getStoreCustomer()[i] << endl;
        }
    }
