Please Help

Convert the following C Language program to ARM assembly language program by hand coding. The program essentially computes two different totals of numbers with even and odd values. The ARM assembly program should work on the KEIL simulator and give the correct result for any size array.

Register assignments: assign myArray to R0, assign tmp to R1, assign even_sum to R2, assign odd_sum to R3. ( You may use temporary registers as you see fit)

C Program:

int * myArray = {23,54,32,11,71,45,68,99};

int num = 8;

main ()

{

int tmp = 0;

int even_sum = 0;

int odd_sum = 0;

for (i = 0; i < num; i++)

{

tmp = myArray[i];

if (tmp % 2 == 0)

even_sum = even_sum + tmp;

else

odd_sum = odd_sum + tmp;

}

}

Solution
