c++ - How do I flush the cin buffer?

Question

How do I clear the cin buffer in C++?

Answer 1

I would prefer the C++ size constraints over the C versions:

// Ignore to the end of file
cin.ignore(std::numeric_limits<std::streamsize>::max())

// Ignore to the end of line
cin.ignore(std::numeric_limits<std::streamsize>::max(), '
')
