Answer 1

1. Limitation of Code Playground code processor. To overcome this, you can do

int dummy {};
std::cin >> dummy;

Before main() returns, to provoke the input dialog.

2. You need to call .ignore() and .clear() on std::cin before you can read <strBuf> in again the second time. Otherwise, only first read will succeed.

Answer 2

Rishi,
I am not sure whether input stream and output stream flushes in-sync. As I understand, `std::endl` flushes the output stream, but I'm not sure whether it also flushes the input stream.

I only know this one ...

Ipang ooh, tnx. But I have another doubt too. I ran this in Cxxdroid, I gave input
"Hello!
Hello!"
But it didn't take the second "Hello!". I know it's because of the newline being in the input buffer, but std::endl should flush it right?

Also, are there any other ways to flush output buffer?
