Why is semicolon used at the end of every program statement?

Semicolons are end statements in C. The Semicolon tells that the current statement has been terminated and other statements following are new statements. Usage of Semicolon in C will remove ambiguity and confusion while looking at the code.

What is the purpose of semicolon in the program?

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).

What does a semicolon do in R?

A semicolon always indicates the end of a statement while a new line may indicate the end of a statement. If the current statement is not syntactically complete new lines are simply ignored by the evaluator.

What is the use of semicolon and curly braces in C programming?

Semi-colon ; acts as a terminator in C/C++. Whenever Compiler encounters a semicolon, it breaks the flow there and everything written after ; will be considered a different statement. Everything written between the curly brackets is considered to be a part of while loop.

Does R need semicolon?

(!!!) Solutions to this: (a) Use emacs, it helps you to detect some such errors, (b) Try to use semicolons, even though R doesn’t need them, (c) You have to signal to R that an expression is incomplete – e.g. put “y = 2 + 3*x +” on the 1st line, so he knows something is to come.

Why don’t we use semicolon in Python?

It is NOT PYTHONIC. Python is supposed to be clean and readable. Syntactic characters like semi-colons add unnecessary clutter. If you send a code like this to an experienced Python programmer, you will never hear the end of it.

Why do we use curly braces in C?

In C and other C like languages curly brackets are used to provide a clear demarcation point for the beginning and end of a block of code. The compiler reads the open curly brace as the start point, the code executes, the closing curly brace marks the end, and the code moves out of scope.
