how to store in array in MIPS assembly language?

A[k++] = A[k] + A[k]
# i-> $s0, k-> $s1 , base of A[] ->$s2

i tried the following but can't figure out how to store back in array A[k++]....

sll $t0 , $s1 , 2
add $t0 , $t0 , $s2
lw $t1, 0($t0)
add $s1, $t1 , $t1 # i added A[k] + A[k]

In order to iterate throught arrays in MIPS, you need to add 4 bytes for each position of the array. Example:

.data
  myArray: .store 12 # array with length of 3 (3 x 4 bytes)
.text
  li $t0, 0
  li $s0, 1
  sw $s0, myArray($t0) # myArray[0] = 1
  addi $t0, 4
  sw $s0, myArray($t0) # myArray[1] = 1
  addi $t0, 4
  sw $s0, myArray($t0) # myArray[2] = 1
