Summing an array in assembly x86. On the inputted indexes -


im having trouble adding array on inputted indexes. example, user inputs 4 starting , 6 ending array have loop through array[4] array[6] , add numbers inclusively. i'm not sure if can use array in .data in arraysum procedure. have push procedure somehow?

i using kip irvine's external library this.

my code here:

 title assignment 7      include irvine32.inc   .data str1 byte "the array sum is:    ",0 start byte "enter starting index:  ",0 endinx byte "enter ending index:    ",0  array dword 4, 6, 2, 5, 6, 7, 8, 4 sum dword ? j dword ? k dword ?  .code main proc     mov esi, offset array     mov ecx, lengthof array      mov edx, offset start     call writestring     call readint     mov j, eax     mov esi, j       mov edx, offset endinx     call writestring     call readint     mov k, eax     mov ecx, k      call arraysum     mov sum,eax     call writeint  main endp  ;--------------------------------------------------- arraysum proc ;sums array falling within j..k inclusive ;---------------------------------------------------     push esi     push ecx      mov eax, 0 l1:     add eax, array[esi]     add esi, type dword     loop l1      pop ecx     pop esi     ret  arraysum endp  end main

you should have no problem accessing array arraysum, seems code loop wrong. loop label instruction decreases ecx register , jumps label if ecx not zero. array contains dwords means when access elements should multiply index 4. overall code loop should this:

    push ebx     mov ebx, offset array l1:     add eax, dword ptr [ebx + esi * 4]     inc esi     cmp esi, ecx     jle l1      pop ebx

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
