Write a program to add ten numbers from 0 to 10 or Convert following C language to ARM assembly Language.

void main()
{
int sum;
int i;
sum =0;
  for (i=0;i <10;i++)
  {
  sum = sum +1;
  }
}
--------------------------------------------

AREA myData, DATA
COUNT EQU 10  ; we will test count upto 10
SUM   EQU
  AREA MYCODE, CODE
  ENTRY
  EXPORT __main
__main
  LDR r0,=COUNT
  LDR r1, =SUM
  LDR r2, =1  ;r2 stores the initial vale of i Myloop
myloop
  ADD r1, r2, r1  ;sum = i + sum
  SUBS r3, r0, r2 ; r3 = r0-r2 (check if r0 and r2 are equal)
  BEQ stop  ;Branch to stop label if r0-r2=0, Z=1
  ADD r2, r2, #1  ; increment i
  BNE myloop  ; if flag not set then do the loop again
stop 
  B stop
  END
