Coding. Where to start?
Hey,
so basically iv never had anything but macs my whole life. I like them their superior. I think that the mac community makes the best apps round. Now iv recently become interested in coding. All i know so far is that coding = Making an application/script/whatever. I get confused the minute anyone even mentions anything technical. I would like to start to produce my own products, but have no idea were to start, i have Xcode and thus far all i can do with it is sit there and look puzzeled. can someone give me a heads up on coding and a run down of the basic steps so I (the future) have some were to start. I have an idea of a product I would like to make but have no idea how to implement it. I would appreciate any help what so ever. I realize that this is probably biggest thing to ask of you but it will pay of eventually when you get to be apart of the worlds best application beta  . cheers |

sounds like im in the same boat as you. I'd really like to know this.
two sites were pointed out to me on this forum for cocoa. Havent looked at them yet but they are:
http://www.cocoalab.com/
and
http://www.stanford.edu/class/cs193e/ |

First thing you should learn is about programming basics like:
conditional statements (if... else)
loops (while,do...while,for, etc)
THEN THE MOST IMPORTANT:
Buy a book or take a course on program design.
I have seen a lot of really good coders write absolutely crap programs simply because they were badly designed and ended up becoming unmanageable (including myself).
The other thing you should do is learn a bit about relational databases and data modelling basics.
Then onto a bit of SQL.
A lot to learn LOL, I'm still learning. I am now doing Java programming and I am lucky to be in a Mac friendly workplace.
Anyways, good luck with it, the world needs some decent programmers

Get a book. Work on lots of practice applications before you start on your dream app. If you start your dream before you have the experience you'll only become frustrated with it.
Some people suggest learning C first. I don't think that's strictly necessary if you get a good book. Unfortunately, I can't recommend any as I started Cocoa programming after having a fair bit of experience with other languages and object-oriented programming.

Also, try the developer documentation that comes with xcode, there's a fair bit of info there.
there's a nice little ebook you can get for free on using xcode, here: http://www.cocoalab.com/BecomeAnXcoder.pdf

A good start is something like UNIX for Dummies, as it shows you how to work in the Terminal. From that, you learn about shell scripting and the like, which is a great intro.

I started out with Java, then learnt C.
This is how it is at USYD.
You then move onto C++.
In the process you learn other things such as UNIX shell scripting, SQL and then depending on the subjects, you learn things like PHP, AJAX, .NET and other things...
Start with the basics first though, as someone suggested. I started with Java for a year (uni, two first year courses).

So go get some books as people have suggested, and start reading. When you get stuck, and have made some attempt by yourself to get unstuck, you should ask for help.
We're going to be able to help you when you get stuck. We are not going to be able to teach you how to program. Your earlier posts seem to show some confusion about what is actually involved. We can't just tell you the "magic words" that will allow a program to fall fully formed from your mind into an Xcode project.
Find some books, take a TAFE course or get a bachelors degree in either Computer Science or Software Engineering. Feel free to ask questions when you get stuck. |

I concur.
Having spent the last 9 1/2 years of my life working with a 25+ year old database application, I am painfully aware of how important design is. Of course the other side of the coin is "don't get caught up in design hell".
This is some of my favourite code:
Code:
Q N R,Q,C,D,E,W,B,G,H,S,T,U,V,F,L,P,N,J,A S N=$G(N),Q='N,F=Q+Q,P=F+F,W=$L($T(Q))
S W=$E(W,Q),S='N_+N,W=W-F*S,L=$G(L),R=$C(Q_F_P),R(F)=$C(F+Q_F),R(P)=$C(W-F) W #
S T=$E($T(Q+F),F,W\S)_$C(W+S+F) X T S B=$P(T,$C(P_P),F),C=B\(W*W),D=B-(C*W*W)\W
F G=S-Q:F:S+F+Q S E=B-(C*W*W+(D*W)),H=$E($T(Q),G),@H=$S(@H<S:'Q,Q:N)_@H,T=C_D_E
F A=Q:Q:W\S S J=$E(T,A),C(F)=$S(J>(F+Q)&(J<(S-F)):Q,Q:+N),C(P)=$S(J#F:Q,Q:+N) D
.S C(Q)=$S(J<(S-F):+N,Q:Q),C(F+Q)=$S(J>Q&(J<(S-F))&(J'=(P+'L))&(J'=(P)):Q,Q:+N )
.S H('L)=L F S H(N?.E)=$O(C(H('$G(N)))) Q:H('+L)=L S F(A,H('L))=C(H(W[(W\S)))
F U=Q:Q:P W !,R F V=Q:Q:P+F W $S(F(V,U):'Q,Q:$C(P_(W\S))) W:'(V#F) $C('N_F_F+F)
W !!,R(F)_C_R(P)_D_R(P)_E_R(F) X $RE($E($T(Q),Q+F,P+Q))_R(P)_'N W # G:N=L Q+F Q

If you don't know, find out. Nobody will be there to spoonfeed you (sorry, it's true!). Do a bit of research, look through some tutorials or basic sites to familiarise yourself and build upon that.
Basically... the only way to become good is to practice, read a lot, understand the material, practice, practice... try your hand at different scenarios/problems and look for patterns etc.
Start small, a "hello world" program for example will even help!
