unbalanced braces around else statement and warning by
braces {} are not necessary for any arm of this statement.

"Check: braces {} should be used on all arms of this statement";
"Check: Unbalanced braces around else statement";

and 1 warning of type:
"WARNING: braces {} are not necessary for any arm of this statement".
