如何循环阅读控制台输入? [英] How Do I read Console Input in a loop?

问题描述

我正在使用G ++ 4.7.2编译此代码，并且很难连续读取来自控制台的输入.代码看起来像这样.

I am compiling this code with G++ 4.7.2, and I am having a hard time continually reading input from the console. The code looks like this.

//Ensure the CIN buffer is clear & empty from previous reads
std::cin.clear();
std::cin.ignore(INT_MAX, '\r');

std::string uInpt;
std::getline(std::cin, uInpt);

while (uInpt.compare("quit") != 0)
{
  std::cin.clear();
  std::cin.ignore(INT_MAX, '\r');
  std::cout << "You entered: " << uInpt << std::endl;
  std::getline(std::cin, uInpt);
}

我遇到的问题是:
1.似乎根本没有清除CIN缓冲区，原因是因为，我只能在循环开始之前输入1个字符，然后似乎已经有一个回车符.
2.在循环中，我似乎从未得到过读取提示.

有想法吗?

The problem I am having is:
1. It seems like the CIN buffer is not cleared at all, the reason being is because, I can only ever input 1 character before the loop starts, Then it seems like there is a carriage return already in place.
2. I never seem to get prompted for the read while in my loop.

Thoughts?

推荐答案

是的.问题出在将代码放在派生进程中并让父进程消失.

Yea....That doesn''t really work. The problem came from having this code in a fork''d process and letting the parent process go away.
