return 0;
}

as this are the errors the output finds:

..\Playground\: In function 'int main()':
..\Playground\:18:5: error: expected ';' before '}' token
}
^

Answer 1

add ; after int main() and add ; after ...default case"

Answer 2

my mistake. dont add ; after main().
place bracket sign "{" after main().
if there is space between main and (), delete it.

Answer 3

Just add a semicolon in the cout statement of default case.
You do not need to add break statement in switch case int the last case i.e. default

Answer 4

add break; at end of default section
