Question

Programming 5. The following design will input numbers into an array or doublewords, using the sentinel value -9999 to terminate nbr Elts-= 0; get address of array prompt for and input number while number -9999 loop add 1 to nbrElts store number at address add 4 to address prompt for and input number end while; Implement this design in a windows 32 program that uses a dialog box to prompt for and input each number. Assume that no more than 100 numbers will be entered. Use a single message box to report the sum of the numbers, how many numbers were entered (not counting the sentinel value), the average of the numbers, and the count of array entries that are greater than or equal to the average value.

Explanation / Answer

Solution:

code:

.MODEl FLAT

INCLUDE io.h

;exit process declaration

ExitProcess PROTO NEAR32 stdcall, dwExitCode:DWORD

;declaring constants

car           EQU 0dh

lineFedd EQU 0ah

AllowedCnt    EQU 100

.STACK 4096

;data section

.DATA

info      BYTE 'Enter up to 100 numbers'

getInput BYTE 'Enter value?',0

enterVal BYTE 20 DUP (?)

nbrElts       DWORD ?

myAry         DWORD AllowedCnt DUP(?)

mySum         BYTE 10 DUP (?),car,lineFedd,0

sumStr        BYTE car,lineFedd,lineFedd,'The sum is'

cntStr BYTE car,lineFedd,lineFedd,'The number of elements is'

;code section

.CODE

_start:

     output info

     mov nbrElts,0

     lea ebx,myAry

     output getInput

     input enterVal,20

     atod enterVal

while: cmp enterVal,-9999

     je whileEnd

     inc nbrElts

     mov [ebx],eax

     add ebx,4

     output getInput

     input enterVal,20

     atod enterVal

     jmp while

    

whileEnd:

     mov eax,0

     lea ebx,myAry

     mov ecx, nbrElts

     jecxz endExec

forLoop: add eax,[ebx]

     add ebx,4

     loop forLoop

     dtoa mySum,nbrElts

     output cntStr

     output mySum

     dtoa mySum,eax

     output sumStr

     output mySum

    

endExec: INVOKE ExitProcess,0

PUBLIC _start

     END
