Should you comment every line of code?

You should write a comment on every line of code.

How do I reduce the number of lines in code?

1. Decide on the logic first and then start coding. If you start coding with no pre determined logic, the code may go on for many lines.
2. Use ternary operators in place of small if else blocks. Reduces 5-6 lines into 1.
3. Review the code. You might end up reducing lots of unwanted lines.

How do I know how many lines of code?

Cloc can be used to count lines in particular file or in multiple files within directory. To use cloc simply type cloc followed by the file or directory which you wish to examine. Now lets run cloc on it. As you can see it counted the number of files, blank lines, comments and lines of code.

How many types of code review techniques are there?

Types. Code review practices fall into three main categories: pair programming, formal code review and lightweight code review.

How can functions reduce the amount of written code?

Functions can also be shared with other programs, reducing the amount of code that has to be written from scratch (and retested) each time. Testing — Because functions reduce code redundancy, there’s less code to test in the first place.

What is a comment in C programming language?

Comments are especially important in large projects containing hundreds or thousands of lines of source code or in projects in which many contributors are working on the source code. A comment starts with a slash asterisk /* and ends with a asterisk slash */ and can be anywhere in your program. Comments can span several lines within your C program.

How do you comment out multiple lines in C?

The compiler will assume that everything after the /* symbol is a comment until it reaches the */ symbol, even if it spans multiple lines within the C program. You can create a comment that displays at the end of a line of code. In these examples, the compiler will define a constant called AGE that contains the value of 6.

How to add source code comments to C source code?

Comments are typically added directly above the related C source code. Adding source code comments to your C source code is a highly recommended practice. In general, it is always better to over comment C source code than to not add enough. It is important that you choose a style of commenting and use it consistently throughout your source code.

Should every single line of code have its own comment?

In these worlds, a coding standard that calls for that every single line of code to have its own comment is not the right answer. Neither is forgoing comments. OTOH, making comments subject to code review is exactly the right kind of standard for critical software. It makes for more reviewable and maintainable code, but this comes at a cost.
