Shapes/Calculation program

kryz (4)
Ok... I might be missing something or whatever in the program. The assignment is to allow user to enter in a shape and its dimensions in a file. Also, to calculate the area, perimeter, volume, and/or surface area of all the shapes in the file that the user has entered. I tried to compile the program and its not showing up anything? I might be missing something and its not complete with the calculation for the shapes. I just want the basic thing to show up then do the calculation later. I'm using the gcc/g++ compiler and they're accurate version which works with my other cpp programs.

Here is the program:

You seem to have coded all the prompts, but you don't actually perform any calculations.

I know.. I stated that I didn't put in any calculations yet. Anyways, I got it fixed to show up. Have an issue right now which its in the filestreaming to append data. It's only able to record first part of the shape but it refused to record the second shape?

You have it set up so that the person inputting data from the keyboard creates a new file and then the shape is stored in that file. Do you need to create a new file each time the program is run based on what the "user" (person typing) designates or could you just create one file that all the shapes are put in to?

It should be just one file for user to create to put all shapes into.

"I tried to compile the program and its not showing up anything?"

Does this mean the compiler is not showing anything or that when the program is run it doesn't output anything?
kryz (4)
Nevermind about that. It was compiler issue that I've installed wrong. Although, other post about appending data is which I've got it fixed. So, thanks all for trying to help! ;)
