Join Todd Perkins for an in-depth discussion in this video Understanding how programming works, part of Programming for Non-Programmers with iOS 7.
…So, how does programming work?…In programming, there are three steps.…Writing the code, compiling the code, and running the code.…Writing code involves creating computer commands in a human readable language.…While there are a lot of code specific things…in here, like braces, and semi colons and equal signs.…You'll also notice a lot of English words.…Void, view did load, super, value string and mode.…
So using a human readable language, we're able to write commands for a computer.…The next step is to compile the code.…In Xcode, compiling is called building.…Building translates your human-readable code into…a language that a computer can understand.…In addition, compiling creates an app file known as an executable.…If this process sounds complicated, rest assured knowing that all you…have to do is click a button for this to happen.…In compiling the code, you could also designate some lines to be ignored.…
These lines are called comments, and…comments are prefaced with two forward slashes.…You can use comments to temporarily enable or disable a line of code,…
