Xcode help

g_bash

hello everybody, Thanks in advance for your help.

I started using Xcode recently with no problems until i tried adding more than a file.cpp to my project. the problem i'm experiencing is whenever i try to add a new file to the project i'm working with and compile and run, my window screen only gives me the output of the original file saved in that project. anyhelp plz?? im programming C++ btw. cheers
