Why would a programmer use comments?

Comments are text notes added to the program to provide explanatory information about the source code. They are used in a programming language to document the program and remind programmers of what tricky things they just did with the code and also helps the later generation for understanding and maintenance of code.

Should you comment every line of code?

You should write a comment on every line of code.

Why are comments useful?

They can easily understand the logic behind solving any problem. If you see/edit code later, comments may help you to memorize your logic that you have written while writing that code. ... Writing comments may take time, but it maintains the international coding standards.

Do comments affect how a program runs?

Once you have an executable file, the comments are long gone and will have absolutely no effect on the execution time of the program whenever you run it. But comments in an interpreted language like Javascript and python can make speed slower because it checks the program line by line.

How do programmers find coding errors?

The savvy statistical programmer can use the following techniques to find and eliminate logical errors: Test the program on simple cases for which the result of the program is known. Break down the program into a sequence of basic steps and independently test each component.

What are programming errors?

Errors are the problems or the faults that occur in the program, which makes the behavior of the program abnormal, and experienced developers can also make these faults. Programming errors are also known as the bugs or faults, and the process of removing these bugs is known as debugging.

When developers make mistakes when coding We call these mistakes?

Testing is the process of identifying defects, where a defect is any variance between actual and expected results. “A mistake in coding is called Error, error found by tester is called Defect, defect accepted by development team then it is called Bug, build does not meet the requirements then it Is Failure.”

What is error explain different types of errors?

An error is something you have done which is considered to be incorrect or wrong, or which should not have been done. Type of error - : There are three types of error: syntax errors, logical errors and run-time errors. (Logical errors are also called semantic errors).

How many errors are there in programming?

There are three kinds of errors: syntax errors, runtime errors, and logic errors. These are errors where the compiler finds something wrong with your program, and you can't even try to execute it.

Should I comment before or after code?

In the US, at least, the de facto standard is commenting either before the code or on the same line following the code. Writing your comments after the related code invites a drug test, a psychiatric evalutation, and/or a date with a pair of pliers and a blow torch.
