Hi everyone, I'm just getting my feet wet with Obj-C here. I'm going through Stephen Kochan's Programming in Objective-C 2.0, and have gotten stuck on this small problem. Basically, I'm trying to add two numbers. I could easily do this the C way, by declaring 2 variables (either predefined or using scanf to get user input) but in doing it the Obj-C way, I am here: However, I'm having two issues. One, im getting "error, 'total' undeclared (first use in this function)" in my "- (void) print; " method implementation, and secondly, the total readout says "5+7=0". What am I doing wrong here? Thanks in advance!
