Giving Command line arguments in Xcode in C program

I am solving my C assignment in Xcode and in that program i have to give command line arguments when running the program and for this i have to user terminal like this:

./a.out myfirstCommand mySecondCommand

I was wondering if it possible to give these kind of commands within xcode instead of going to terminal. Thanks

As of Xcode 4.x I've had to go to the Product menu, select "Edit Scheme", then select the arguments tab and add the arguments there.

Keyboard shortcut is commandshift<

Pre Xcode 4.x
Right click the executable in your Xcode project and pick "Get Info". Then pick the "arguments" tab and you can set arguments to pass when you run or debug your program from inside Xcode.

Xcode 4.x or later
Go to the Product menu, select "Edit Scheme", then select the arguments tab and add the arguments there.
