The orange region is the original green region before main() ========= Adding a ';' is like a adding an empty (null) statement. So it can be inserted at where a statement can be added. Adding a "{}" is like declaring a scope. So it can be inserted at where creating new scope makes sense. So you can insert a ';' or "{}" in the "green" places, but will get a warning in the "yellow" spot. You can insert a ';' in the orange area, but you cannot insert a "{}" there. Compiler will issue an error if you insert them somewhere else. You may insert a ',' or "()" after <iostream> ("yellow region"), but you will get a compilation warning. ',' cannot be inserted anywhere else. --
