hello trying concatenate 2 strings. i load strings 1, 2, & 3. need store final string in r2. i load strings memory using ldr , can store them using str . code anyone know effective way concatenate them? adding them above not right? registers limited 1 byte of data maybe doing else wrong.. i noob. sonething that. assume strings aren't null terminated because doesn't appear in code example. also you'd want store string1 , string2 in .text section (read permanent memory), while string3 .data section, since buffer in ram. ;stings aren't \0 terminated (like in c) should deal size ourselves mov r4, #string1_size loop1: ldrb r3, [r0], #1 ;copy string1 srtring3 strb r3, [r2], #1 subs r4, #1 bne loop1 mov r4, #string2_size loop2: ldrb r3, [r1], #1 ;copy string2 string3 strb r3, [r2], #1 subs r4, #1 bne loop2 ;done

is there way cast unhandled exception line "input string" in "correct" int "format"? don't remember work around type of incompatible implicit conversion...unhandled exception @ statement in first loop. public class arraytest { public static void main() { // initialize array int[] myarray; console.writeline("enter size of array"); int arrayvariable = convert.toint32(console.readline()); myarray = new int[arrayvariable]; console.writeline("element @ index {0}", arrayvariable); console.writeline("enter elements of array"); (int = 0; < arrayvariable; i++) { myarray[i] = convert.toint32(console.readline()); } (int = 0; < arrayvariable; i++)// display array elements { console.writeline("element @ index {0} {1}: ", ...

i'm looking way parse text url has been provided user, parser script has been provided user. eval easy enough, super scary. end goal allow user point server data source , tell server how read data. what best safest way this? python or node preferred, i'm not limited specific language. so example. cvs document, i'll have text file. url: http://www.ams.usda.gov/mnreports/lm_xb803.txt this python script can read file url, , stored on database: expected_length = 6 requiredfeilds = ['low','high'] requirednonzero = ['low','high'] response = urllib2.urlopen(url) reader = csv.reader(response) grade = none date = none first_row = true keep_list = [] row in reader: if len(row) != expected_length: continue if first_row: date_text = row[2] date_object = datetime.strptime(date_text, '%m/%d/%y') date = date_object.strftime("%y-%m-%d") first_row = false row_label = row[0].strip() row_...

is there way, similar using if let and/or optionals, test whether index empty buffer in swift? define own: extension array { func ref (i:int) -> t? { return 0 <= && < count ? self[i] : nil } } the ref() function returns optional, can nil , , can use if let syntax access returned value ref() when exists. use such: var mya = [10,20,30] if let val = mya.ref(index) { // use 'val' if index < 3 } else { // if index high }
