Hi all, im a newb with some java experience, playing around with the xcode. however, i just installed xcode and startet a new "cocoa application" projekt (macosx). i opened "Other Sources" => "main.m" and replaced the code in there with these lines: when i hit "build and go", shouldnt that print the line "The sum of 50 + 25 is 75" on terminal ??? i dont understand why it doesnt work. can someone help me out? thanks a lot!
