Great Video, the ending kind of surprised me.

"For all have sinned and fallen short of the glory of God - Romans 3:23"

are bible versus necessary in the code?

[Integr8d]

I made a mistake, when I assigned values to the variables. I typed c = a = b; Everything else was correct. The output was a + b = 2. I'm guessing it's a semantic issue, as the program returned 0. But why did it do that?

[khaledacmilan]

Thank you very much man, I really appreciate your efforts , all lessons are very useful for me!.

why would you write 3.5e1 instead of just 35?

[Ivarvw]

@forumpaul Some people prefer to use exponentials also for numbers such as 35, 100 or 5, just to keep things clear. 35, 3.5e1 or 3.5*10^1 all mean the same, so it doesn't really matter at all.

[OxyPinecho]

@forumpaul 3.5e1 is scientific notation so it wonted work if it's 35 it has to be between 1-9

When you went into XCode which project did you select?

Thanks.

[jellymelly829]

can you maybe give us a download link for the powerpoint in there? thanks

[zamoray123]

make sure you put  for example: NSLog(@" This is a Program %i , anyVariable");

[Dudeman0911]

when you run the console and both the values come up zero, for me b still comes up as some huge number

[gblax123]

@IntenseSNEZZLIN it's just decimal points, so you are correct.

[nolongerloner]

Thanks for the effort! I find your explanation provides me with a very smooth learning curve. Thank you very much

[itrooper]

Thanks, I'll give that a try later, Cheers.

@phishphony Make sure when you create the program that the type is Foundation

[MRRSENA]

This is great, simple..

[MPX4132]

oh... nice, hey can you please upload the presentation somewhere so that we can download it for notes, that would make it easier for me to study... Nice vid ThumbsUP! XD

[itrooper]

I'm wondering why NSLog is coming up black on mine, even though it's typed exactly the way you have it and I get !Expected expression before '@' token when I Build and Run the script :(

Any clues?

[macandcomputerhelp]

@itrooper Make sure when you create the program that the type is Foundation

[Riccio1981USA]

@itrooper NSLog = printf now when you do code use printf for the NSLog

[MrJonnyrocks]
