HLA PROGRAM $7$: Tuition Calculator

Write an HLA Assembly language program that calculates the cost of tuition at SMC$.$ Different choices will be represented by a bit field as shown below:

$`$A Resident?

Parkingecal?

Since just $8$ bits are being entered, your program should expect to read $2$ hexidecimal digits.

The four low$-$order bits $($shown in orange$)$ represent the number of enrolled units. Your code should ensure the value is not zero.

The next two bits $($shown in purple$)$ represents the term. Some of the different fees various based on the term of enrollment. $00$ means Fall, $01$ means Winter, $10$ means Spring and $11$ means Summer

The next bit $($shown in red$)$ represents whether a student is a California resident. $0$ means non$-$resident, $1$ means California resident

The high$-$order bit $($shown in blue$)$ represents whether a students wants to buy a parking decal for this term. $0$ means no parking decal, $1$ means parking decal.

Based on these choices, here are the fees that apply to students this Fall $2024$:

Below are some sample program dialogues that demonstrate these ideas.

$($Hint: Do this in small steps, bit$-$by$-$bit. There's alot to it$...)$

$($Further Hint: You can read hex numbers by reading directly into a register. Just don't use EAX since stdin.get uses that one when it executes.$)$

$($Final Hint: Since we haven't learned how to do multiplication yet, although it's kinda painful, I was expecting that you would perform the multiplication by a looping set of addition instructions$)$

Feed me$(2$ hex digits$)$: $00$

Units enrolled cannot be zerol

Feed me $(2$ hex digits$)$: $01$

$1$ Unit$($s$)$

Fall

No parking

Non$-$CA Resident

Tuition: $$374$

Feed me$(2$ hex digits$)$: FF

$15$ Unit$($s$)$

Summer

CA Resident

Parking

Tuition: $$715$

Feed me$(2$ hex digits$)$: $6$F

$15$ Unit$($s$)$

Spring

CA Resident

No parking

Tuition: $$690$
