What's the benefit of case-sensitivity in a program language? -

is there advantage of being case-sensitive programming language?

my first programming experiences basic family (msx basix, q-basic, vb). these not case-sensitive. now, might because of these first experiences, i've never grasped benefit of language being case sensitive. on contrary, think source of unneeded overhead , bugs, , still annoys me when use e.g. java or c.

now, read on clojure (a lisp-dialect) , noticed - surprise - 1 of differences lisp case-sensitivity.

so: benefit (to programmer) of having case-sensitive language?

the things can think of are:

  • double number of symbols
  • visual feedback , easier reading complex variables using techniques camelcase, e.g. hopcount

however, first argument doesn't hold because of being major source bugs (bad practice use hopcount , hopcount in 1 method).

the second argument doesn't hold either, decent ide can provide in other way. example vba ide, has approach: langauge case-insensitive type variable change case used in definition. example, if defined dim thisismyvariable string, change occurrence of thisismyvariable thisismyvariable). provides programmer immediate clue variable typed-in correctly (because changed appearance).

edit: added ... benefit to programmer ...

one point is, said, visual aid. programming languages (and frameworks) have conventions on how capitalize variables, names, etc. also, enforces using uniform names everywhere, don't have mess same variable referred "var", "var" or "var".

i can't remember of ever having bugs related capitalization, point seems kind of contrived me. using 2 variables of same name different capitalization me sounds conscious attempt shoot in foot. different capitalization conventions everywhere signify objects of different type (classes, variables, methods , on), it's pretty hard make such mistake due different semantics.

i'd think of in way: gain not having case-sensitivity? introduce ambiguity, encourage sloppiness , poor style.

this subjective matter of course.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

visual c++ - Using relative values in array sorting ( asm ) -

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
