I resolved this from another post on mac rumors - youtube vid replied by VPrime: http://www.youtube.com/watch?v=ZU_MT9PwKkk thanks for all who viewed anyway! JB My original thread post from this morning: "I'm a programming beginner and am attempting to run a simple C++ console program for Xcode version 3.2.3. Build was successful but I cannot run it. "Build and Run" icon is grayed out as well as any of the "run" items in the menu bar. Does anyone know where I went wrong?"
