the double semicolon ends the definition of types / functions / objects...
the single semicolon ends a statement. So to end the definition of print_logic 
you need the double semicolon in your example.
There are cases where you can omit the double semicolon, I write them allways, 
for visual aid ( and I can search for them in my editor).

the same way as to printf, without delimiters:
print_logic true false
