c++ - 将整行整数读入 vector

请看下面的代码

int main()
{
    cout << "Enter numbers (-1 to stop entering; -2 to exit)" << endl;

    while(cin>>enterNumber)
    {
     numbers.push_back(enterNumber);
    }


    for(size_t size=0;size<numbers.size();size++)
    {
        cout << numbers[size] << endl;
    }
}

我在这里尝试做的是这样的

输入数字列表(例如:1 2 3 4 5 6 7 8 9 0 11)

将它们全部读入 vector

打印它们

在这里，当我按回车键时，什么也没有发生!似乎循环没有退出。当我按下回车键时如何打印值？

更新

我按照答案中给出的建议编辑了代码。

int main()
{
    cout << "Enter numbers (-1 to stop entering; -2 to exit)" << endl;

    std::string line;
getline(std::cin, line);
std::istringstream iss(line);
while (iss >> enterNumber)
{
    numbers.push_back(enterNumber);
}


    for(size_t size=0;size<numbers.size();size++)
    {
        cout << numbers[size] << endl;
    }
}

但它现在给出了另一个错误

"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf

BUILD FAILED (exit value 2, total time: 1s)

最佳答案

使用 getline 将 cin 中的一行读入字符串。然后将该字符串放入 istringstream 。然后从该 istringstream 中读取，而不是您现在使用 cin 的位置。

std::string line;
getline(std::cin, line);
std::istringstream iss(line);
while (iss >> enterNumber)
{
    numbers.push_back(enterNumber);
}
