Get all the user input with EOF?

Question

I'm having problems getting all the user input from the terminal. It's always one line short, and it's the last line.

do{
    getline(std::cin, input);
    buffer += input;
    buffer += '\n';
}while(!input.empty());

gives me the desired output, but it ends when I press Enter, and I want it to end when it reaches End Of File(EOF), when i press Ctrl+D. I have tried

while(!(std::cin >> input).eof()){
    buffer += input;
    buffer += '\n';
}

but it doesn't get the last line. Adding the input to the buffer after the while-loop also doesn't solve it.

Answer 1

Keep reading input with getline:

std::string buffer;
std::string input;

while (std::getline(std::cin, input))
{
    buffer += input;
    buffer += '\n';
}

When you input EOF getline will set eofbit and the loop will end.

In any case the second snippet should store the last input as well.
