I have a working program but now I have to use the int argc and char *argv[] parameters to main. Whenever I try to do this it gives me errors that it cannot save. Is there any way to make argc and argv work in Eclipse?
I guess your problem is that you don't know hot to pass argument to you program, when you execute it through eclipse isn't it ?
If that is what you want, read the following.
Click on the "Project->Properties" then in "Run/Debug settings" click on the "New button". Choose C++ application. Here you can see that there are 4 tabs, and the second tab is called "arguments". In this tab you can see a textarea. Type your application's argument there, and click "OK". When you will execute your application thanks to the "play" button of eclipse, your program will be called with arguments.
