The semicolon is the statement delimiter. It's not part of the instructions, it separates them. It's just a hint to the compiler, it doesn't generate any code in itself.

Generally speaking, there's no relation between the length of the source code and the size of the binary file, particularly because the length of thevisiblesource code is typically much smaller than that of all the libraries used.
