C ++:ctrl + d终止程序(ubuntu) [英] C++: ctrl+d terminates program (ubuntu)

问题描述

(C ++的新手)

我有这个简单的代码(为问题简化了):

I have this simple code (simplified for the question):

 int main()
{
    string currInput;
    while (getline(cin, currInput))
    {
    }
    cout << "wont be printed" << std::flush;
    return 0;
}

我已经调试了一段时间，我可能会错过一些东西:

I have been debugging for a while and I probably miss something:

运行它并按 ctrl + d (在某些字符串之后或立即)时，它不会打印while循环之后的字符串.它只是停止运行.我认为这可能与冲洗有关，所以我也添加了这一点.我想念什么?

When running it and pressing ctrl+d (after some strings or right away), it does not print the string that is after the while loop. It just stop running. I thought it might be something with flushing so I added that too. What am I missing?

PS:在调试中运行时，它会提及有关叹气信号的信息.

PS: When running in debug, it mentions something about sighup signal.
