Yes, many times. It also takes out anything in angle brackets, so #includes tend to get lost.
The posted code needs to be marked as preformatted text (using the </> button in the toolbar, or ctrl-shift-C), and then there shouldn’t be any problems. And as a bonus, it retains the indentation too.
#include <iostream>
while (t--) {
if (x == '*')
cout << "something in quotes\n";
}
