i want understand how declaring variable char saves memory declaring int or short. know fact declaring char reserves 1 byte in memory while 2 or 4 bytes reserved int. now, suppose in 16 bit processor, variable char stored @ location 0xabcd. since 16 bit processor, 1 byte or 8 bits of 16 bits @ address 0xabcd reserved char. int variable stored @ location 0xbcde, accordingly reserve 16 bits of 16 bits available @ location 0xbcde. want know happens 8 bits @ location 0xabcd left on after reserving memory char variable considering fact @ 1 memory location 1 variable can stored. memory addresses not work "variables". can not store 8 or 16 bits, can only , exclusively store exactly 8 bits (one single byte). (a) when int gets stored "at" address, takes more space -- not "in" same address, flowing on in next memory addresses, following "the" memory address. thus, if store char @ 0xabcd, compiler knows it's safe assume next value ...

my objective is: - find files owned selected user - delete them my current code: @echo off /f %%f in ('dir /b /s') call :delete_file %%f goto :eof :delete_file ( set var=%1 dir /q %var%| find "\user" ) i'm looping files in current directory, i'm calling :delete_file parameter %%f (file path), in :delete_file i'm setting var first received parameter (%1 - file path). , now, i'm parsing again file (with /q paramter - output owner) in search of owner. question is, how set output of: dir /q %var%| find "\user" to variable? if output null, file not owned selected user, otherwise can delete file. how check this? this should echo del command files matching text if happy remove echo keyword , run real. i made text compare case insensitive. @echo off /f %%f in ('dir /b /s /a-d') ( dir /q "%%f"| find /v ":\" |find /i "%computername%\user">nul && echo del "%%f...

this relatively problem i'm stumped. programming in r, don't think problem restricted r. below i've tried write simple code demonstrating problem: f1 = function(x) { return(a + x) } f2 = function(ftn) { return(ftn(1)) } f3 = function(a) { return(f2(f1)) } the problem: if call f3(2) [for example], f2(f1) returned, , f2(f1) returns f1(a+1). f1 not recognize value of 'a' put in f3, code doesn't work! there way can make f1 recognizes input f3? r uses lexical scope, not dynamic scope. functions free variables (variables used not defined within them) in environment in function defined. f1 defined in global environment a looked in global environment , there no a there. can force f1 free variables in running instance of f3 this: f3 = function(a) { environment(f1) <- environment() return(f2(f1)) } this temporarily creates new f1 within f3 desired environment. another possibility if f1 needed within f3 define f1 there (ra...

i want display webpage in book-like fashion, 2 columns, spread through several pages. i using column-count , works fine 1 page, need split text after number of lines display rest in new page. so instead of displaying text as: a b c d e... (each letter represents column of text) i want: a b c d e.. ho this, specifying number of lines per page displayed (and number of columns, although in case 2) , automatically arrange javascript? thanks help. you forgot, each space rendered column! however, cannot use css break line @ each character, either use max-width: 5px; /* approximately 1 char */ or you'll use jquery break string @ each character , write appending <br /> line. var chars = "a b c d e f"; chararray = chars.split(" "); /* @ white space */ (int = 0; < chararray.length; i++) { /* write , add <br /> @ end */ } this way can handle it.
