Question

Write a MIPS assembly program to first set up 10 bank accounts. Store the 10 account numbers in an array named Accounts and the 10 balances in an array named Balances (hard-code them into your program). Your program will then repeatedly read in an account number, a transaction type (0 for deposit and 1 for withdraw), and a transaction amount. Your program will display the new balance after the transaction. An error massage will be printed if an incorrect account number is entered. A withdraw request will be rejected if not enough fund is in the account. Your program will terminate when -1 is entered as an account number.

Use following account numbers and balances to initialize the arrays:

Account Balance

205 123

212 5000

200 4

203 79

201 987

231 500

209 40

207 904

211 33

250 200
