naming-conventions

What's the official way to write: Xcode , XCode , xcode , ... ? I have seen it writing numerous ways and want to be sure that I use it correctly. a picture is worth a thousand words 来源： https://stackoverflow.com/questions/5725269/official-way-to-write-xcode

I have several files "2011-01-01.txt", "2013-01-02.txt", "2015-02-01.txt", etc. I wish to create a struct variable for each of the file such that (the values are made up): machine20110101.size=[1,2,3]; machine20110101.weight=2345; machine20110101.price=3456; machine20130102.size=[2,3,4]; machine20130102.weight=1357; machine20130102.price=123; machine20150201.size=[1,2,4]; machine20150201.weight=1357; machine20150201.price=123; And, save('f20110101.mat','machine20110101'); save('f20130102.mat','machine20130102') ; save('f20150201.mat','machine20150201'); As we can see, the struct names are

Is there some purpose for this convention? Apple likes to use underscores to mean "private", according to the Coding Guidelines for Cocoa : Avoid the use of the underscore character as a prefix meaning private, especially in methods. Apple reserves the use of this convention. Use by third parties could result in name-space collisions; they might unwittingly override an existing private method with one of their own, with disastrous consequences. Method names beginning with underscores are reserved according to The Objective-C Programming Language (which means they're reserved even if you don't

So here are two functions that do almost the same thing. How would you name each one, if you had to include both in your project? void strToLower1(char* str) { int len = strlen(str); int i; for (i=0; i<len; i++) str[i] = tolower(str[i]); } char* strToLower2(const char* inputStr) { char* str = strdup(inputStr); strToLower1(str); return str; // must be freed } EDIT: I modified the above example for code-correctness (sheesh) I really like the Taligent Coding Standards , especially the naming conventions . The convention about using special names for copy, create, and adopt routines may apply here

"TLD-first domain-like identifiers" is a mouthful but that's all I can come up with. I've seen these used in various places over the years and wondered what the history/reason behind this convention is, since you might be forgiven in thinking that there is one true way to mention a domain. I don't use Java but I recall from poking around that namespaces are often done like this: uk.co.tophats.stitchkit A specification file for a "Launch Agent" on Mac OS X: ws.agile.1PasswordAgent.plist A preferences file on Mac OS X: com.apple.iTunesHelper.plist Why is the TLD first? Is it just hierarchical

I'm a web developer with no formal computing background behind me, I've been writing code now some years now, but every time I need to create a new class / function / variable, I spend about two minutes just deciding on a name and then how to type it. For instance, if I write a function to sum up a bunch of numbers. Should I call it Sum() GetSum() getSum() get_sum() AddNumbersReturnTotal() I know there is a right way to do this, and a link to a good definitive source is all I ask :D Closed as a duplicate of c# Coding standard / Best practices Classes should be in camel notation with the first
