Coding Standards
-
I am the programming department of my company, and I still adhere to point 2 almost religiously. It goes with the idea of self-documenting code: if I come to a piece I'd written some time earlier and need to remember the type and initialized value for
PersonId, I know where to look. I can look at the top of the code block much faster than I can pull up and use a search tool. As for point 1, I find that commenting "obvious" code is useful: what may be obvious today, when writing it, will not be so obvious when I have to revise the code four years later. My personal standard, though, is to make comments meaningful.Gregory.Gadow wrote:

Coding standards with my employer are strange based on everything I've ever known, everything I've ever read, everything I've ever been told. They are set in their ways and I don't think anything could change their mind on these internal standards. Here are a few: 1. Excessive commenting -- practically every operation in code has a preceding comment. No matter how descriptive the code is, and no matter how simple the operation may be, there is a comment such as the following:
/// /// This is an addition method.
///
private int Add(int a, int b)
{
// Add the two numbers and return the result
return a + b;
}private void Process(MyFileObj myFile)
{
// Make sure the parameter is not 'null'
if (myFile != null)
{
// Strip all the bad data from the object
myFile.StripBadData();// Add the file to the collection \_myFileCollection.Add(myFile); }}
2. Variable declaration -- this may not be so bad, so please correct me if I'm wrong. But I've never seen it done this way. According to their standards, all variables in a method must be initially declared at the top of the method, before anything else is done:
private MyClass MyMethod()
{
int count = 0;
MyClass someObj = null;// Iterate over the file collection foreach (MyFileObj file in \_myFileCollection) { // Make sure the file's name is not longer than 20 characters if(file.Name.Length <= 20) { // Copy the file to a new location file.CopyTo(@"C:\\SomePath\\" + file.Name); // Increment the counter count++; } } // A lot of other code // ... // Setup the class that will be returned someObj = new MyClass(); someObj.FileCount = count; // Return the class that has the data we need return someObj;}
The "MyClass someObj" isn't referenced until the very end of the method. Why should it be declared at the very top of the method? Maybe I'm missing something? I've never declared objects until the time I need them. These are just a few examples. There are some other things I don't really agree with, but I can't change any of them.

The comments I add are generally for myself, especially if it's a method, control or a class I've never used before I find it useful to help me understand the implementation, especially if I know I will be using it again. I don't add the obvious // Add two numbers // Return obvious value but I might add the // Add X and Y here or the later result will have a phase offset type comments. I should add that I don’t recall the last time when someone stopped by or emailed with a request for an explanation as to how my code works or how to use it. (They may question the methods but not madness. :))
It was broke, so I fixed it.

Now how is anyone supposed to understand that code with the single comment you've provided? Surely it should be:
// Setup the class that will be returned
someObj = new MyClass(); // Create a new instance of the MyClass class and store it in the someObj variable.
someObj.FileCount = count; // Store the value of the count variable in the FileCount property on the instance of the MyClass class stored in the someObj variable.There, isn't that better? :rolleyes:

Ideally, every coding standard rule will have a rationale as to what benefit the rule brings. Variables should be defined as close to their first use as possible in general. If they are re-used several times, I always redeclare them every time in a new {} block within the method to not accidentally re-use a value from the previous block. Those comments are silly, you are exaggerating there, right? If not, the comments are such that you could possibly generate them with a tool (think of e.g. GhostDoc). It would even be a nice exercise to write such a tool! :) Edit: code comment should mostly explain why something is being done, not what is being done, because the what is mostly self explanatory, or can be found out using debugging. The why is very hard to find out.

I'm not joking in the least about the commenting standards. If it were allowed, I would paste an untouched, large block of code, or even share a file, just to put it out there.

I find both these standards odd. I've been using RCG (Ravi's Commenting Guidelines™) for 20 years and they have served me and my teammates well. The guidelines are simple:
- Strip out all code within blocks (except block delimiters - i.e.
if,do,for,whileandswitchcode boundaries). - The remaining code and comments should clearly represent the method's psuedocode. If it doesn't, you need to add comments.
The coding standard about declaring all local variables at the start of a method is complete nonsense, IMHO. To maximize readability, local variables should be declared on first use within the block to which they're scoped. This would cause me to rewrite your example method thusly:
/// /// Performs a file copy (a better comment is required here).
///
/// The result of the operation.
private MyClass MyMethod()
{
// For each file whose name is less than 21 chars...
int count = 0;
foreach (MyFileObj file in _myFileCollection) {
if (file.Name.Length <= 20) {
// Copy it to the new location
file.CopyTo(@"C:\SomePath\" + file.Name);
count++;
}
}// A lot of other code // ... // Return result MyClass someObj = new MyClass(); someObj.FileCount = count; return someObj;}

That's an interesting concept, and I may try and adapt that style of commenting. It's simple to understand and I believe it may work nicely. Even if they don't want to change it, I may adapt it for my personal coding standards. Thanks for the input, Ravi. :)

When Code Complete was first published there was actually a chapter dedicated to this. The idea was that you would design your code with comments. It would go something along these lines... step 1 was to write comments of how the code would work.
// an add method to add two integers
// add the two integers and return the resultYou could in theory then have a review meeting of just those comments. This in turn causes you to get a better understanding of what you are trying achieve. step 2 was to add the code
// an add method to add two integers
-(int)add: (int)a b:(int)b
{
// add the two integers and return the result
return a+b;
}More importantly is that if you did step 1 properly then in theory someone else could do step 2 just by implementing your comments. we did something similar at my first programming job out of college (20++ years ago) and it helped in slowing things down to get you thinking before writing. I don't follow it to the same detail today but I do find at times when I am working on something a bit complex to follow similar steps. think of it like a mental dump of what you are thinking at the time you write the code. we have all asked the question when reading someone else's code.
What were they thinking when they wrote this piece of code?
I would take the time to learn more of how and where these standards started. there is generally a wisdom or history behind things like this and knowing that can help more than the actual standard itself.

Very informative. I appreciate it. As previously stated, my manager has extensive experience with multiple languages. And I'm almost certain it came from quite a long while ago. Also, they have a lot of contractors (myself included) come through here. So I'm thinking the extensive commenting style may be in place to more or less protect future contractors and such from becoming easily confused. Who knows, I could be wrong.

Declaring all variables at the begining of the method is an old c++(i am not sure if it comes from c) standard closely connected with the variable block of sight. In c# i dont believe there is such thing. Today i was sooo close of declaring such variable
bool bResultBecauseMyBossDoesntLikeMoreThanOneReturnInTheMethods = false;
next time ask your boss if you need to put a comment to the line
i++;
Sometimes i wonder... why does they want us to comment everything like the next "programmer", who will manage this will be a monkey.

The problem with that entire statement however is it means that either code reviews are not occurring at all or that they are not being taken seriously. If code reviews are done correctly then an incorrect comment should not show up.

There are no good uniform standards for commenting code (no intelliSense either) and despite best efforts issues with code comments are missed even by best reviewers. One of the more practical approach is using asserts and exceptions instead of comments. When meaningful comments are necessary I also add time stamp showing comment/code updates.

The examples you gave are excessive. The declaration of variables at the top is actually a hold over from C programming.
But C# is not C. Is it necessary? I've learned throughout the life of this thread that it doesn't matter. It isn't necessarily good or bad. But does it benefit in any manner when coding in C#?

whether it benefits in any manner is only a question that can be answered by those who created the coding the standards you are speaking of. from a language perspective though it makes where the variables are defined if you referring to code performance getting improved.

I see very little - if any - benefit in declaring all local variables at the start of a method. To the contrary, it's bound to cause problems: 1. Variables that are being used much later may not have to be allocated at all, depending on the flow of control. You may end up spending resources and processing time for the initialization (and release) of data you never need! This is specifically true if you make a sanity check on the method arguments (which you alwys should) and go for a premature return. 2. When you maintain the code, it's often useful to see how a local variable has been initialized. This gets harder when the variables are grouped a long way up, and you can't see at a glance whether it's being changed between the declaration and the spot you're about to edit. 3. You shouldn't keep a hold on resources that you no longer need: the only way to reliably and maintainably (is that a word?) free up the resources required by a variable is declaring it within a code block. I even sometimes use a code block as a means to denote a specific variable's lifetime! You (or your manager) might consider this just as a'nice to have' feature, but it quickly becomes a necessity when you program concurrent threads using locks. There's no way in hell you're going to keep your locks over an entire method! P.S.: 4. How do you do exceptions? I suspect your manager has never implemented a catch block, did he? :doh: 5. Why do you think C++11 has been changed to end the lifetime of for loop counters at the end of the loop?
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

A very good point indeed. You might even extend that to the trivial example of commenting a statement like
i++;
For one you may want to comment on why you chose to use post-increment rather than the more efficient preincrement. ;) Or, better yet, you might comment on why you need to increment this variable at this precise moment - or what it is counting anyway! ;P

Well, I'm going to have to dock you points for not commenting every line of that code. Without the comments, how is anyone supposed to understand it? :rolleyes:
