Write a Console program, let users to enter prices calculate subtotal, tax, and total.

Phantasy [73]

Answer:

Explanation:

This is a project I already submitted, but I never received feedback. All my upcoming assignments will be based on this, so I wanted to make sure it is correct. I got this program to work as far as calculating the information, but I was hoping someone could please let me know if it meets the parameters/requirements?

I did attempt it. It works and adds the items exactly how the example showed in the video. However, I wanted to make sure my code is solid, and not just a mishmash or working because I got lucky, and if there is a better more solid way to do this I want to make sure I can. I do want feedback so I can learn and get better and I am trying my hardest. I always right out all the code I see here and try it and learn what it does piece by piece, because it helps me learn and improve. I also want to make sure it is going to work once I start the code for the next half of the requirements.

i cant really help they dont let us put codes on here

Lossless compression decreases file size without removing any bits of information. Instead, this format works by removing sameness within data to reduce the overall file size. With lossless, it is possible to perfectly rebuild the original file.

<h3>What utilizes lossless compression?</h3>

Lossless compression is commonly used for so-called "discrete" data, such as database records, spreadsheets, word-processing files, and even some types of image and video information. Text compression is a powerful area for lossless compression.

<h3>What is lossless compression example?</h3>

Lossless compression methods are reversible. Examples of lossless reduction include GZIP, Brotli, WebP, and PNG, Lossy compression, on the other hand, uses inexact approximations by dumping some data from the original file, making it an irreversible compression process
