It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. It looks like someone you know made a statement on this. While case folding is fairly trivial in English, it's much less so in some other languages.
OTOH, "ss" is equivalent -- would you consider a compiler obliged to match them? When you get into Unicode, you get even more interesting tterms, such as characters with dies diacritical marks versus separate vaiable diacriticals. Then you get to some Arabic scripts, with three separate forms of many letters, rather than just two. In the dark ages most programming languages were case-insensitive almost out of necessity. For example, Pascal started out on Control Data mainframes, which used only six bits per character 64 codes, total.
Most such machines used the "CDC Scientific" character set, which only contained upper-case characters. You could switch to other character sets, but most had either upper-case or lower-case, but not both -- but used the same codes for both. By the time more capable hardware was widely available, their being case-insensitive was so thoroughly ingrained that changing it was impossible. At least IMO, compiler should take input exactly as presented, not decide that "you wrote this, but I'm going to assume you really meant something else.
Why would anyone WANT case insensitivity? Case insensitivity is exasperating. In Java case sensitivity is NOT used to provide termz options in code, but rather for a very clear and consistent semantic what does variable mean in computer terms. It does NOT provide greater freedom: it allows you to pack some information concisely into what is an otherwise overly verbose language.
I think that in explicitly statically-typed languages with mucho compiler and IDE support, what does variable mean in computer terms is a great way to communicate information e. With languages varjable Ruby, case insensitivity signs of a broken down relationship probably cause even MORE unexpected results, though I'd be open to trying case-insensitive Ruby. I think that case sensitivity with a strict system does not obfuscate code but actually makes it clearer.
Consider possible Java variqble. In Java as-it-is, you would automatically know what this is. In case-insensitive Java, it's ambiguous, so you'd need to resort to some other mechanism to differentiate classes from instances from packages from methods. And THAT mechanism would computwr make you vomit with how ugly it is :.
With case-insensitive parsing, you'd be restricted to having to use unique identifiers, since 'myClass' and 'MyClass' would be the same thing. Alternatively, you'd have to add layers of complexity to your parser to make sure you could determine which identifier is used based on context. Suppose the XmlWriter class also has a static method called "Write". Are you calling it on the instance or on the class, if there is no case-sensitivity applied here?
I don't think it was "implemented" so much as "allowed. That's almost certainly why it ended up in C; they wanted to make a simple language that was easy to implement a compiler for, at the expense of usability. As for why it's in modern langauges? Because it's in C, of course, so it how to find the slope intercept form of a line on a graph be the right way to do it!
I typically program in Python, but back in my C days, I found it very convenient to name class instances the same as the class, but lower or camel case as others have said :. Using case-insensitive languages requires some other convention for this, i. I also find it convenient to grep case-sensitively to find reference to a class vs. With a case-insensitive language, this would be less easy. Lastly, as a programmer, when I see words with different cases, it jumps out to me that they are different things I rarely have bugs where variable cases were wrong, even in dynamic, scripted languages where a compiler would have helped.
People pay attention to the shape of words before they actually read them. Case kn keeps the shape copmuter a symbol consistent throughout code. I also agree with those above that state that different conventions denote different types of symbols. Case sensitivity and insensitivity can both be abused. Bad programmers will always generate bad code Take language as an example. Why do we doee sentences and named things with capitals Is it also because of unix? I think for statically-typed lanaguages like C and Java, it doesn't actually add any value.
Because in most cases, you've got an IDE that'll auto-correct case mismatches for you anyway, so at the end of the day, if I type in "VAriable" by accident, my IDE will auto-correct that to "Variable" for me. Dies to that the MyClass myClass; style conventions and you can see that case-sensitivity is not necessarily a bad thing.
For dynamically-typed computrr, there might be more of an argument, since it's harder for an IDE to guess an autocorrection, but in the case of dynamically-typed languages, you've already got so much more to worry about in terms of typos that using a consistent casing convention isn't going to add that much more burden. So yes, while there's no real reason languages could not be case-insensitive, there's also no real reason why they should be either.
That article from Scott Hanselman about "SignOn" vs "Signon" was about string comparisons, and nothing to do termx programming languages. I agree that strings that users type in should always compared case-insensitively, but I think that's a different ballgame to vafiable in a programming language. When a language is case-sensitive, I take advantage of it to reproduce conventional case usage in mathematics and qhat. Here is a list by no means exhaustive of some case conventions:.
I just figured it was because of Unix and C - but that's kind of a chicken and the egg problem which only the geezers can answer properly. Because there were chickens on Noah's Ark, chickens came first. Therefore, because GCC runs on Unix, Unix came first, therefore because Unix cares so much for case, C and all its variants and descendants, variaboe anything that imposes curly braces, cares for case. In addition to the excellent answers given so far, I'd like to point out that variablw sensitivity gives you also additional "namespaces".
Take filename as an example. Dealing with Windows filename is more trouble yerms Unix filename because filename in Jean is case-insensitive while filename in Unix i case-sensitive. Back to programming. For class name, method name, variable name, most language do not enforce the naming style rule. Sometimes for the sake of simplicity to do "reflection", we can simply use the "Case sensitive" name to bind to other data source without conversion, or handling the problem of same name but in different case.
I'm surprised by this rant. It hasn't caused any problems so far. Especially some programmer come from the early days of BASIC, where a kn name can only be 2 characters long. And so, when it can be any number of characters, they become very happy. Sign up to join this community. The best answers are voted up and rise to the top.

Even English is case-sensitive in general. Comluter cited example is polish and Polish which are two different terms whose written forms differ only in case and which have different pronunciations and meanings. IMO its better for the programming lang not to be too clever in this regard and let the programmers themselves come up with appropriate written conventions.

What does variable mean in computer terms big question too, if the compiler's going to start noticing different spellings, should it what does variable mean in computer terms you to arbitrarily put underscores in or other "word separators"?
Will it maybe try to "do what you expect" when dooes misspell an identifier? How far will it go? BTW, Ada allows underscores arbitrarily inside of numbers for clarity reasons. Barry: The two are pretty much the same -- almost every other language on earth requires characters that aren't available in ASCII. For that matter, even though we sort of get by, it's really rather restricted even for English -- for example, it forces you to write "coöperation" as "cooperation".
Fortunately, typewriters got people accustomed to such restrictions long before computers came along, to the point that few people even consider the possibility of using all the characters once considered what does variable mean in computer terms.
