How to write a comment in Pascal?

In Pascal, you can write comments to document your code or add explanatory notes. Comments are ignored by the compiler and do not affect the execution of the program.

There are two types of comments in Pascal:

1. Single-line comments: These comments start with "//" and continue until the end of the line. Anything written after "//" will be considered a comment.

Example:

program HelloWorld;
begin
  // This is a single-line comment
  writeln('Hello, World!');
end.

1. Multi-line comments: These comments start with "(" and end with ")". Anything written between these symbols will be considered a comment, and can span multiple lines.

Example:

program HelloWorld;
begin
  (*
  This is a multi-line comment
  It can span multiple lines
  *)
  writeln('Hello, World!');
end.

Comments are useful for providing explanations, making your code more readable, and helping other programmers understand your code. It is good practice to add comments to your code to improve its clarity and maintainability.
