How Do I read Console Input in a loop?

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);
}

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?
