How are comments written in a program?

How are comments written in a program?

Line comments either start with a comment delimiter and continue until the end of the line, or in some cases, start at a specific column (character line offset) in the source code, and continue until the end of the line. Some programming languages employ both block and line comments with different comment delimiters.

What programming language uses for comments?

In FORTRAN, BASIC, and COBOL languages, comments are full lines; and each comment is begun by a specific comment mark in a fixed position on the line. In BASIC, REMark lines start with REM. A FORTRAN comment is indicated by a C in position 1, and only works if the C is in position 1. The comment takes the entire line.

What is the purpose of adding comments?

In computer programming, a comment is a programmer-readable explanation or annotation in the source code of a computer program. They are added with the purpose of making the source code easier for humans to understand, and are generally ignored by compilers and interpreters.

What is a code comment?

Code commenting is the practice of sprinkling short, normally single-line notes throughout your code. These notes are called comments. They explain how your program works, and your intentions behind it. Coders are expected to comment their code to some degree.

What information is important to write in comments?

All programs should be commented in such a manner as to easily describe (in English) the purpose of the code and any algorithms used to accomplish the purpose. A user should be able to utilize a previously written program (or function) without ever having to look at the code, simply by reading the comments.

How do you comment in basic?

To comment keyboard shortcut is Ctrl + K, C and to uncomment keyboard shortcut is Ctrl + K, U .

What is the purpose of adding a comment in the program What are the two ways used to add the comments in Python?

In Python, there are two ways to annotate your code. The first is to include comments that detail or indicate what a section of code – or snippet – does. The second makes use of multi-line comments or paragraphs that serve as documentation for others reading your code.

How do you comment positively?

What are comments in C?

A comment is an explanation or description of the source code of the program. There are two types of comments in C: 1) A comment that starts with a slash asterisk /* and finishes with an asterisk slash */ and you can place it anywhere in your code, on the same line or several lines.

What makes a good comment?

A good comment has no need to include a visible link within its content. Its quality should provide the necessary information, and be influential enough to encourage its readers to find out more. The relevant link is the URL you use when you submit your comment.

What are the 2 types of comments?

Using Two Types of Comments

  • Marginal comments.
  • End comments.

Are there different ways to write doc comments?

Thus, there are commonly two different ways to write doc comments — as API specifications, or as programming guide documentation. These two targets are described in the following sections.

What do you use to indicate the end of a comment?

Line comments generally use an arbitrary delimiter or sequence of tokens to indicate the beginning of a comment, and a newline character to indicate the end of a comment. In this example, all the text from the ASCII characters // to the end of the line is ignored.

What’s the difference between block comment and single line comment?

The first is called a single line comment and, as implied, only applies to a single line in the “source code” (the program). The second is called a Block comment and refers usually refers to a paragraph of text. A block comment has a start symbol and an end symbol and everything between is ignored by the computer.

What kind of comments are used in programming?

The flexibility provided by comments allows for a wide degree of variability, but formal conventions for their use are commonly part of programming style guides. Comments are generally formatted as either block comments (also called prologue comments or stream comments) or line comments (also called inline comments ).
