Why we attach ; at the end in C or C++?

Question

The question is in the title: why we have to attach ; at the end of the line in C or C++ languages? Is there any good things if we attach ; at the end?

Answer 1

there must be something which tells the compiler that statement has ended , here we have ;

developers could.have made another choice but its just their will hence we have ;
some programming languages like python dont have ; but instead they use indentation(extra spaces) .

Answer 2

it is like ". "We use the end of the sentences ".", the compiler uses ";"

Answer 3

in every language there is a sign for showing kind of sentence, for example we put '?' to show our sentence is questioning.
in c++ ';' shows that you completed your sentence for definition variables and structural statements.

Answer 4

the compiler don't know if the line is ended or not. So it need a character to say the line is ended, just like the . in English. So you can write your program like this

printn("this is
something");

without a error.
