MIPS programming software named MARS

need help in in english

thank you

Negative transaction values

correspond to checks drawn on the checking account and positive transactions values

correspond to deposits into the checking account. The program terminates when a value

of zero is read in. After each transaction the new calculated balance is displayed.

Run this program. Use the single step feature to observe the contents of the registers as

the program executes. Set a few breakpoints in the program and observe the results.

Notice that this program only works for integer values.

The program includes a heading with a place to insert your name. The program also

includes to-do items like pseudo code explanation of newly added code with < > at

different places within the code. This program provides an example of how all of your

programs should be documented in this course. The syscall instructions are calls to

system services to perform input\output functions.

Run this program and input two deposits in the amount of 1234567890. You will notice

that this program does not contain any instructions to detect when overflow occurs so it

produces an erroneous balance when overflow does occur. Your job for this

programming assignment is to make improvements to this program so that whenever an

overflow does occur in either the positive or negative domain the following specific

announcement will be displayed:

Overflow Occurred Transaction Ignored

Next the correct previous balance should be displayed on the following line in the

Balance column. Then the program should prompt the user for the next transaction.

No message other than the one specified above is acceptable!

Be sure to place in-line comments within the program everywhere you have made

changes to the initial program. Each of your comments should be preceded by #### to

make it easy to find your modifications to the initial program.

------------------------------------------------------------------------------------------------------------

The grading rubric is as follows

Comments and style = 2 points

Program improvement

1.Detects overflow = 3 points

2.Prints announcement of overflow = 2 points

3.Displays correct previous balance = 3 points
