Applications Table Of Contents: Fill & Download for Free

This is a table of contents.You’ll notice that there are named section headers for various sections to neatly arrange and organize the book.You’ll notice the author didn’t put all of the text of his book inside the table of contents. Then why do we do this in programs? (that is: why do we put all of our code in one place?)In programming “we” have a tendency to put all of our code inside the “table of contents” instead of organizing our thoughts. Why? All the people here answering “functions are for re-usability, so you don’t repeat code.” are in fact correct, but there are many more valid reasons to segregate your code, much like a table of contents.For example, clearly this book is about fishing, just from the table of contents, but if I need to know more about Lures, I know exactly where to look. In programming, if I have a function named “getAllUserNamesUpperCased(users);” I know that this function extracts all user names from users, regardless of the data type, and that they will be upper cased. If that is in fact all the function does, I know that the bug breaking the users age is going to be somewhere else. Perhaps something to the effect of : “getUsersAge(users);” (notice that in both instances they’re easier than trying to parse every single “for(int i = 0; i < users….)” because they’re named! They were given a label telling me exactly what data I’m interested in. A for loop can’t necessarily do that by itself.)Imagine if you will, that all of the text from the section about salmon fishing was slapped in the middle of the boat fishing section. Now the author knows that salmon and boat fishing can only be done in the summer, so he put all of that inside the summer fishing section. How easy do you think it would be to find the page about Salmon Fishing, lost somewhere without a section header? The author organized his thoughts into categories, where each thought can be paired with other relevant thoughts, making it easier to understand for the reader. We should do this with our code.Your functions should read like a table of contents. In the following code example, you can probably tell that I’m running a graphical application that depends on the Operating System just by reading this next block of code. Imagine what this function would look like if I had to get registry information, read the date and time, send a request to some server, call a stack of OpenGL functions bootstrapping the graphics library (which is usually dozens of lines of code).function main()  {  InitializeStartingValues();  var osValues = GetOperatingSystemEnvironmentVariables();  var context = StartGraphicsBootstrapProcess(osValues);  MainOperatingLoop(context);  } ^^This main function reads like a table of contents. I know what kind of program this is, I know what the function is doing at a high level, and I know where to look if I am trying to look for some specific code, because its so well organized! If I’m interested in why my graphics library isn’t starting correctly, I know where to look. If I need to look at drivers issues, that’s likely in the GetOperatingSystem… Otherwise if there is some problem with the core features/business logic of the program, that’s all likely inside the MainOperatingLoop somewhere.And guess what? It’s the same all the way down. All the way until the lowest levels of code, you functions will look like tables of contents, making it incredibly easy to understand what all of your code does at every level!THAT is why we use functions.

I’m going to make some scientific assumptions:I’m still the same human I was before getting the opportunity to make a choice between the above two boons.The Universe is infinitely large.Let’s consider the Book of Knowledge option.First off, the book has to provide information on a rather large topic, the Universe. Infinitely large, too. What do I reckon would be the size of such a book? Infinite? Ever-expanding?How long would it take me to read through the book? Infinity? Nah, I don’t have that much time on my hands.Does my having the book guarantee that I understand everything I read in it? Probably not, like all books.Does every Secret of the Universe I get to learn have any applications? Feasible ones? Does this even mean I get to learn something new at all? What if the first 10000000000000000000000 (or more) secrets are just things that have already been discovered?Now consider the One trillion (US Dollars, I presume) above. No matter what kind of Dollar that is, that effectively makes me the world’s richest man. That could easily translate, with some strategy, to the World’s Single Most Powerful Man. I think all my material needs are covered at this point. In only one step; accepting the donation.If I’m interested, I could invest money into any research I wanted to undertake after getting rich. I don’t have to do anything I don’t want to any more.I’d take the money over the book every time. Thanks. Also, I may become benevolent and start aiding the poor and needy, persons far poorer than me, poor persons like Bill Gates.Has a nice ring to it, doesn’t it?For those who are thinking about a Table of Contents in the Book of Knowledge:I think even if it’s summarized to be an infinitesimal (extremely small) fraction of the rest of the book, the Table of Contents would still be infinitely long, as long as that fraction is finite. At least, that’s how Mathematics would say it.Attempting to move from the Table of Contents to the actual content, for me, is just like having to read a Quora post where I have to click the following link an infinite number of times:… (more)
