1. Write a MIPS assembly language program that asks a user and reads in a number

Question

1.                  Write a MIPS assembly language program that asks a user and reads in a number of months to rent an apartment and how many bedroom to have.
Then it should compute its total rent, based on the following:
If the number of rooms is 1 and the number of months to rent is less than 6 (and more than 0), then the rent will be $600 x the number of months.
If the number of rooms is 1 and the number of months to rent is greater than or equals to 6, then there is a discount of $200, and the rent will be $600 x the number of months - $200.
If the number of rooms is 2 and the number of months to rent is less than 6 (and more than 0), then the rent will be $900 x the number of months.
If the number of rooms is 2 and the number of months to rent is greater than or equals to 6, then there is a discount of $300, and the rent will be $900 x the number of months - $300.

If the number of rooms a user chooses is not 1 or 2, then print out the message: "Sorry, we have only one or two bedroom apartments. "

Objectives:

-write assembly language programs to:
            -perform decision making using branch instructions.
            -use syscall operations to display integers and strings on the console window
            -use syscall operations to read integers from the keyboard.

The following shows how it looks like in a C program:

Here is a sample output (user input is in bold):

Please enter a number of months to rent an apartment:
5
Would you like to rent an apartment of one bedroom or two bedrooms?
Please enter 1 or 2:
1
Your total rent: 3000 dollars for 5 months

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

Here is another sample output (user input is in bold):

Please enter a number of months to rent an apartment:
7
Would you like to rent an apartment of one bedroom or two bedrooms?
Please enter 1 or 2:
1
Your total rent: 4000 dollars for 7 months

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

Here is the third sample output (user input is in bold):

Please enter a number of months to rent an apartment:
9
Would you like to rent an apartment of one bedroom or two bedrooms?
Please enter 1 or 2:
2
Your total rent: 7800 dollars for 9 months

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

Here is the forth sample output (user input is in bold):

Please enter a number of months to rent an apartment:
4
Would you like to rent an apartment of one bedroom or two bedrooms?
Please enter 1 or 2:
3
Sorry, we have only one or two bedroom apartments.

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

Explanation / Answer

Hi,

I Will give clear solution for your work to complete.

Step1:

this above code can be converted in this way,

step 2:

For this code you include this type of MIPS solution.

this code can be changed by below MIPS form

tips :

blt $t0, $t1, L1 // Branch if $t0 < $t1

ble $t0, $t1, L2 // Branch if $t0 <= $t1

bgt $t0, $t1, L3 // Branch if $t0 > $t1

bge $t0, $t1, L4 // Branch if $t0 >= $t1

sol: for above statement : you include step 1 solution

Step 4:

from this above all code you should change your code like this

and if you want to branch condition you include

bne and beq $r1, $r2, label // for conditional branches

slt and slti $rd, $rs, $rt    // set if less than (w/ and w/o an immediate)

or                $rs, $rt, imm

by above details make code is very easy.

    li   $v0, 1 or 4    // service 1 is print integer   move $a0, $t0      // move register to be printed into argument register $a0   syscall
