Answer:

Did you mean layer 3 switch? Because a router always operates at layer 3

Explanation:

If the answer is yes, then a layer 3 is a switch that combines the functions of a switch and a router. So it is capable of operate layer 2 and layer 3. Some of its benefits are: Support routing between VLAN, decrease network latency because the packets don’t have to make extra hops to go through a router and reduce security management. But they are really expensive and lack of WAN functionality so they are used mostly for large intranet environments.

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
