c++ - 在 c++ 中，我的程序会自动转到下一个 CIN 提示符，而无需用户添加输入

Question

这是我的代码：

#include <iostream>

using namespace std;

const int SENIOR_PRICE = 9;
const int ADULT_PRICE = 12;
const float CHILD_PRICE = 6.95;
const float TAX_RATE = .06;

int main()
{
        string name;
        string address;
        int numSeniorTickets;
        int numAdultTickets;
        int numChildTickets;

        cout << "Enter customer name:" << endl;
        cin >> name;

        cout << "Enter customer address:" << endl;
        cin >> address;

        cout << "How many senior season tickets?" << endl;
        cin >> numSeniorTickets;

        cout << "How many adult tickets?" << endl;
        cin >> numAdultTickets;

        cout << "How many child tickets?" << endl;
        cin >> numChildTickets;

        return 0;
}

用户输入姓名后，系统会提示他们输入地址。但在他们输入地址之前，它还会提示输入高级季票的数量。为什么它会跳过一行输入？这是发生的事情：

Enter customer name:
Daniel Benson
Enter customer address:
How many senior season tickets?
5
How many adult tickets?
5
How many child tickets?
5

Answer 1

cin >> 名称;

仅将输入带到空间。因此，如果您打印变量name，您将得到Daniel. 如果您打印变量address，您将得到Benson. 因此，就程序而言，它已将两个字符串作为输入。

通过在输入后打印变量来证明上述陈述。

您可能希望使用cin.getline()将空格分隔的字符串作为输入。
