I am new to this forum, and new to programming, although I have already reached chapter 18
of Programming in C textbook.
Please, take a look at the program I typed in from the book, and warning messages I receive.
I would be grateful for explanation on what I am doing wrong. I work on Mac OS 10.7.5, Xcode 4.6.3,
1) I created a file with the command:
touch prog18-2.m// Program ot work with fractions - Objective-C version
#import <objc object.h="">
printf("The numerator is %i, and teh denominator is %i\n", [my_fract numerator], [my_fract denominator]);
[my_fract free]; //frees the memory that was used by Fraction object
3) I compiled it with:
gcc -framework Foundation prog18-2.m -o prog18-2
4) Terminal generated the following:
prog18-2.m: In function ‘main’:
prog18-2.m:58: warning: ‘Fraction’ may not respond to ‘+new’
prog18-2.m:58: warning: (Messages without a matching method signature
prog18-2.m:58: warning: will be assumed to return ‘id’ and accept
prog18-2.m:58: warning: ‘...’ as arguments.)
prog18-2.m:71: warning: ‘Fraction’ may not respond to ‘-free’
I would like to limit the image taken to fixed size w=5 in and h=10 inch.
1. There is a way to display on screen (when taking the picture) frame in this size?
2. After taking the pic, how to enable moving the picture so the user can center the image in the 5x10 frame

Could be anywhere. You need to do some debugging for yourself and identify where things are going wrong. Then edit your question and add the detail to explain exactly what is or is not happening that should be. Also please put <pre></pre> tags around your code so people can read it clearly.
