Awesome! I'm understanding it instead of just memorizing it! Thank you so much!

[gblax]

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

[khaledacmilan]

[MrJonnyrocks]

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

[macandcomputerhelp]

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

[itrooper]

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

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

@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.

Great Video, the ending kind of surprised me.

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

[zamoray]

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

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

[basquesp]

Hey man thanks for the video but is a bit confusing for me too, I saw that on the left side you have something program.m but the way you got there wasn't explained.

Sorry I'm noto meaning to criticise just trying to understand I am a bit raw on the subject....

[FVenancio]

Hey, I just discovered your videos and they're awesome! You make it easy and fun to learn! I just have one question, NSLog works to debug the program right?

I'm asking because these terms are confusing at first and I'm new to the whole programming scene...

Thanks again for the great videos!

[Nehalkarim]

Please make new videos with the new Xcode?

[Cappucade]

Can someone help meh;
What does NSLog Stand for?

[OxyPinecho]

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

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?

[Dudeman]

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

[phishphony]

When I type in NSLog is comes up black and it doesn't come up red even though I typed it exactly. When I debug it, it says Expected expression before '@' token.
