Program $1$:

Enter the code from below for Roman Numerals.

Program $2$:

Software Sales

A software company sells a package that retails for $$99.$ Quantity discounts are given

according to the following table.

Write a program that asks for the number of units sold and computes the total cost of

the purchase.

Input Validation: Make sure the number of units is greater than $0.$

Output: Show Cost of Service and Show their Discount $($savings$).$

Program $3$:

Bank Charges

A bank charges $$10$ per month plus the following check fees for a commercial check$-$

ing account:

S$.10$ each for fewer than $20$ checks

$$\mathrm{.}08$ each for $20-39$ checks

$$\mathrm{.}06$ each for $40-59$ checks

$$\mathrm{.}04$ each for $60$ or more checks

The bank also charges an extra $$15$ if the balance of the account falls below $$400($before

any check fees are applied$).$ Write a program that asks for the beginning balance and the

number of checks written. Compute and display the bank's service fees for the month.

Input Validation: Do not accept a negative value for the number of checks written. If a

negative value is given for the beginning balance, display an urgent message indicating

the account is overdrawn.

Output: $5$ lines of output with decimals lined up$.$ Show Bank Fee, Check Fee, Low

Fee $($either $0\mathrm{.}00$ or $15\mathrm{.}00$ and The Total Fee.

See Supplemental section for input and output how$-$to

Gradesheet for Branches Programs:

ALL programs must compile and be thoroughly tested

Do not tum in code that does not compile

Do not turm in code that has not been tested

ALL Programs must use good programming style $($indenting$,$ variable naming$)$

Place the following Comment section at the top of each program.

$//$Name: your name

$//$Course: COP $2250$

$//$Program Name: Chapter $3$ Roman numerals $($or Sales or Bank Charges$)$

Program $1$: Roman Numerals

Must Compile or Zero points $-$ or $-$ incorrect results loose $\frac{1}{2}$ points

Program $2$: Software Sales

Must Compile or Zero points

Input validation for number of units must be $>0$

Calculations were correct for the range: $1-9,10-19,20-49,50-99,100+$

Must have the Chart for Quantity and Discount Shown on the screen!!

Program $3$: Bank Charges

Must Compile or Zero points

Must show Bank Fee chart

Input validation for negative amount of checks with and Error message. If user enters a negative amount $-$ then only show an error

message with no other stats.

Calculations were correct for the range:

Must display each of these fees:calculated check fee bank fee Low Fee Iotal Fee

Note $-$ Low fee is calculated $$15\mathrm{.}00$ bank fee if beginning balance $<mn\; id="EditorElement\_937534">4</mn><mn\; id="EditorElement\_937535">0</mn><mn\; id="EditorElement\_937536">0</mn>$ or $$0\mathrm{.}00$

List the above $4$ fees on separate lines and decimals must be lined up$.$ See Supplemental, last page
