try compiling your 'program' and check the error messages

int main(){

That was not the important part anyway. Just want to know if reading into a single char can ever set a failbit unless EOF is reached :
1 2

char ch;
std::cin >> ch;

> Can this loop ever be terminated by the fact that failbit alone is being set (not eofbit and failbit together)?
In theory, only if
str.max_size() characters have been extracted into the string and the next character in the input buffer is not
'\n'
In practice, we can safely ignore this possibility;
str.max_size() would be too huge.

No; if the failbit is set, the eofbit will also be set.
