Why semicolon is used in programming?
In computer programming, the semicolon is often used to separate multiple statements (for example, in Perl, Pascal, and SQL; see Pascal: Semicolons as statement separators). In other languages, semicolons are called terminators and are required after every statement (such as in PL/I, Java, and the C family).
Why does CODE end in semicolon?

What is the use of semicolon in C programming?
C# makes use of Semicolon to get rid of ambiguity and confusion as its usage makes the code clear, structured and organised. Like other languages especially C and C++, C# also follows the same rules in the Semicolon application. The absence of Semicolon throws an error by the compiler which has to be rectified.
What happens if there is no semicolon in Scala?
The absence of Semicolon throws an error by the compiler which has to be rectified. It also lets the compiler know the end of the statement.

Is there a semicolon before or after else in Pascal?

What is the role of semicolon in Perl?
Role of Semicolon in Perl: Perl language employs Semicolon after every line, except at the end of the block. Perl lets us omit the Semicolon because it can be used as a separator rather than a terminator. Every statement in Perl is terminated with Semicolon unless it is the last line of the program.
