objective-C: string with variable

Question

I am new to objective-C and I need help adding a variable to a string. in java, to add a variable to a string you have to do something like this:

 output = "Area: " + area + '\n' +"Circumference: " + circumference;

I can't figure out how to put that together to one string.

i have tried:

NSString *answer = [NSString stringWithFormat:@"Area : %.03f", area , "Circumference: %.03f", circumference];

and a couple other ways but it seems to not work.

Objective-C requires you to define the format first and then pass the parameters.

Use this instead:

NSString *answer = [NSString stringWithFormat:@"Area : %.03f Circumference: %.03f", area, circumference];

First I would say you need to learn more and see books and other references like.

here is how you will do in objective c

 NSString *answer = [NSString stringWithFormat:@"Area : %.03f Circumference: %.03f", area , circumference];
