How do you get input until a newline in C++?

Question

I'm reading input using cin . If I leave the input blank (and just hit enter), the cursor moves to a new line and asks for input again. Is there any way to make cin or scanf just return an empty string in this case?

Answer 1

Instead of operator>> , use getline .

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

Side note: There's no recursion involved here. Recursion is when a function calls itself, that's not happening here.
