Intro to Coding - Readable Code

What are the best ways to improve the readability of code? Choose all that apply. Be consistent when naming variables, procedures, classes, and methods while you are writing. Use comments to include helpful information about the program for future use. Use indenting and line breaks to keep your code from being a solid block of information that is difficult to follow. Use # symbols as the first character of all variable names.

You are writing a recursive code segment. Which of the following would be the most helpful comment? This code is recursive. This recursive code counts the nodes in a tree. This is efficient code. The purpose of this code is evident.

2. This recursive code counts the nodes in a tree.

Readable code includes the use of color and symbols to make the code look good. consistent and meaningful variable names, helpful comments, and formatting. variable names that do not vary from program to program. comments that include the programmers' reactions to a particular piece of code used.

2. consistent and meaningful variable names, helpful comments, and formatting.

Your program will be used by many departments at the university. Your comments will be important to their IT people. What would be a useful comment? This was a really hard part to write, but it finally works. I'm not sure what this does, but I don't have time to troubleshoot it. This segment returns a value that is used by the segment marked B.

3. This segment returns a value that is used by the segment marked B.

Select the best word or phrase that completes the sentence. Indentation and line breaks can be used to make sure the code takes up the entire screen at all times. create a decorative pattern within the code itself. make it easier to follow the code and identify which parts of the code belong together.
