What is xCode? Provide a GUI editor (like Visual Studio) Provide an interface that includes a project into which program files are loaded (like Eclips and jGrasp) Allow you to compile a program and displays any error messages generated Allow you to run a program and provide an output window with results You can either download the full XCode environment including documentation (2.3GB) or download a stripped-down version that that is about 750MB. If you want to download the smaller version of XCode that doesn't include documentation, click on "Developer Downloads". (Much of the documentation will not be relevant to you when you are just starting to learn C++, and the Apple website itself already makes extensive documentation available.) Click on "Developer Tools" under the "Downloads" sidebar Search for the latest version of XCode (you want something like that looks like "XCode X.Y.Z Developer Tools", for example "XCode 3.2.2 Developer Tools") 1-4 4

How to create a c++ project in xCode? Open xCode, then: “Tools -> C++ Tool” Reference: https://www.cs.drexel.edu/~mcs171/Wi07/extras/xCode_Instructions/index.html Reference: https://www.cs.drexel.edu/~mcs171/Wi07/extras/xCode_Instructions/index.html 1-13 13

Name and Path of the Project 1-14 14

What items are in myProject? In the "myProject" window, you will see that a program named "main.cpp" has been created and installed in the project by default. (Sometimes these wizards are a little too helpful, if you know what I mean.) This program almost certainly does not do what you want it to do, but it is a fully-functioning C++ program. This means you can compile and run it right now. Go ahead, if you must. We'll wait for you to get it out of your system. 1-15 15
