Dave Mark has a great introduction to Macintosh programming that discusses Xcode among other things.

is this only c because i need c++
man i wrote this program up and it doesn't work i need to know how to just change it to compile c++

The Dave Mark book does not cover C++.

You need to create a C++ Tool project. Start Xcode, and choose File > New Project. A dialog box with a list of project types will open. Select C++ Tool, which is in the Command Line Utility section.

If you click the link in my signature, you can find an article that walks the reader through the creation of a simple C++ program in Xcode.

thanks i already figured it out though.
if you could help me with one last thing
when you enter in a variable when running the program how do you write the code so that it can be a decimal. don't you put a % somewhere

float varName = 0;

scanf("%f", varName);

Or, using C++ (like specified), just use cin.

I think you should probably spend some time learning C++. Read http://www.cplusplus.com/ and buy yourself a good book. It will come in handy.

Try not to judge your professors just for that. I had a professor in uni that was like that, but was also one of the few professors who actually knew what he was saying (probably the best in the major at my uni)... not to mention it doesn't look like you can write English very well either

 

[benlangdon]

ya, i know i get it.
she used to work for ibm.
but still i cannot understand what she says.
also, determining my english skills based on how I type on a forum is

why use c++ when surely it would be more straight forward to use Obj-C...
