ambiguouselse.cc: In function ‘int main()’:
ambiguouselse.cc:12:4: warning: suggest explicit braces to avoid
ambiguous ‘else’
---------------------------------
I don't understand the warning here, the situation here is
different as in the documentation for -Wparentheses.
sorry, the spaces got lost, but is ambiguous the correct
wording here? it doesn't result in undefined behavior.
the else couples always with the inner if
i misinterpreted the documentation for -Wparentheses
So never mind and regards
