Aug 3, 2012 1:16 AM Hi, finally I installed Xcode on a Mac OS. This is my first time. I am sure there are tutorials and videos out there, but I would want to be on a right direction without waisting any time. Basically I have made C++ application on PC under Windows 7. What it does it asks for input(s) like number(s) and makes calculations and outputs in a process depending on an entry. It uses for example: scanf("%s",st), cout << , cnn >> , goto Loop; uses a lot of Arrays and so on... It also uses "Enter" key on a key board to input a number. Now, I would like to make an app for iPod touch, like for example at the beginning image will appear, once is double clicked, it would take me to that program enviroment, and it will be asking for inputs and would output the same way on iPod touch window. Now, what type of application I have to make in Xcode? Can I just paste my original c++ code into working enviroment or I have to convert to Objective C ? and if so how to substitute scanf, cout, cnn, "enter" key, goto statement and so on... ??? I am sure there are Objective C tutorials out there, but initially I can paste my original code and compile, and go from there, so to make all necessary changes along the way, is that the way to do it? And also if I want to quit an app I would hit a certain button, and it would quit at any time. So could anyone direct me, give links, and so on... Thanks in advance.
