Question

I have an application that implements an interactive shell, similar to how the Python console / irb works. The problem now is that if the user accidentally hits ^D EOF is issued and my getline() call returns an empty string which i treat as ‘no input’ and display the prompt again.

This then results in an endless loop that prints the prompt.

Now in Python I would solve that problem by catching EOFError, but in C++ no exception is raised I could catch and there doesn’t seem to be a setting on cin to ignore EOF.

Any hints?

Correct solution thanks to litb:

if (!getline(std::cin, str)) {     std::cin.clear();     std::cout << std::endl; }
