I have to create a simple calculator and I dont know what I am doing wrong!
The code I have so far, there are 23 errors I got it down from 42! Now I am stuck and dont know which way is up or down!

What are the errors? Find the first one and fix it and many of the later ones will fall away...

Here is a screenie

I dont know what half these mean. and if I try something to fix it to be corrected then another damn error pops up. Been at this since 10 am this morning. this is the lowest build of errors I have gotten too.

The variables on 10 and 11 (thanks WaltP!) have no type. I would first bring them into main and give them a type.

I would move the struct you declare up and out of main. It's not incorrect to put it in main but personally I think it keeps it better organized outside. EDIT: I realized it was your enum you were referencing in the menu part, so disregard that.

thanks now down to 16 errors!

Go back and pop some code tags around your code, use the edit button and either highlight and press the [code] button in the box, or type the following around your code:
[noparse][code] //code goes here [/code][/noparse].
WaltP (faithful moderator) put them around your last post but try to remember them on your own.

My own clarification:

EDIT: I realized it was your enum you were referencing in the menu part, so disregard that.

I meant that to mean disregard the part I had written previously about using the struct before you declared it.

Okay, so -- remove the entire part between namespace and the enum. To declare a struct up there write the [icode] struct yada {};[/icode] bits around it just like you did when you had it in main.

Here's a hint: look how you've written the names in the enum and look at how you wrote the names when you used them.

So I went from 16 errors to 62. GDI! What am I missing? the struct stuff should be things like my menus? or?

Please look at the code you're posting. Can you actually read it?

Please see this, and maybe we can read it, too.

I meant for you to stick the double addition; in between the { }. I wrote it out shorthand since you'd already had the right syntax when you had declared it in main.

Take a step back and look things up if you have to (or if they don't seem right).

@ThePMan I was just happy that we got the line numbers lol.
