Assignment 1

Due date: Nov. 20, 2023 (Session 002) & Nov. 21, 2023 (Session 001) in class

Instructions:

? Read the Assignment Requirements posted in the UMMoodle before attempting to solve the

following problems with C++ programs.

? Both the hardcopy and softcopy of your assignment should be submitted on time. All

programs (.cpp files) are to be compressed and uploaded to the UMMoodle under the

“Submit Assignment 1” button. The compressed file should be named with your student

number such as “ba12345_Ass1.zip”.

Question 1: Lottery Program (50%)

Write a C++ program that outputs a greeting message at the beginning, then generates 6 positive

random digits with different values ranging from 1 to 9 for a lottery game. The program prompts the

user to input 6 positive digits and then checks if there is an exact match of all the 6 numbers. It will

output different awards for different matches according to the following rules: Win $5000 for 6 correct

matches, $3000 for 5 correct matches, and $1000 for 4 correct matches. Your program should allow

the user to choose to continue or not and will output a message to end the program.

(Bonus part: Try to include some error-checking as shown below.)

Sample Input & Output:

================================

Welcome to the Lottery Program!

================================

Please enter 6 different positive digits: 1 6 2 4 7 3

The 6 drawn numbers are: 3 4 2 6 1 7

You have 6 correct matches! You win $5000!

Would you like to continue (Y for Yes, N for No)? Y

++++++++++++++++++++++++++++++++++++++++++++++++++++

Please enter 6 different positive digits: 5 1 2 7 4 3

The 6 drawn numbers are: 5 3 2 6 1 7

P.2

You have 5 correct matches! You win $3000!

Would you like to continue (Y for Yes, N for No)? Y

++++++++++++++++++++++++++++++++++++++++++++++++++++

Please enter 6 different positive digits: 1 9 2 8 7 3

The 6 drawn numbers are: 8 9 4 6 1 7

You have 4 correct matches! You win $1000!

Would you like to continue (Y for Yes, N for No)? Y

++++++++++++++++++++++++++++++++++++++++++++++++++++

Please enter 6 different positive digits: 1 6 8 9 5 3

The 6 drawn numbers are: 3 4 2 6 1 7

You have 3 correct matches! Sorry, no prize for you!

Would you like to continue (Y for Yes, N for No)? Y

Question 2: Sales System (50%)

A sportswear shop at a certain outlet launches promotional sales during the New Year. It advertises

that all sports-shoes are 10% off. If the customer buys 2 pairs (with each pair being above $200), an

additional 10% off will be applied. If the customer buys 3 pairs (with each pair being above $200),

an additional 15% off will be applied. If the customer buys 4 pairs or more (with each pair being

above $200), an additional 20% off will be applied. For sports-shoes below $200, only the original

advertised 10% off will be effective. For example, if the customer buys 2 pairs priced at $300 each,

the price after discount will be $300x2x0.9x0.9=$486 plus sales tax. If the customer buys 2 pairs

priced at $300 each and 1 pair priced at $100, the price after discount will be

$300x2x0.9x0.9+$100x0.9=$576 plus sales tax.

Write a C++ program that will print the total price that the customer should pay, by asking the salesgirl

to input the sales tax (e.g. input 5 for 5%), the number of purchased shoes, and the retail prices of the

P.3

purchased sports-shoes one by one. The program will help to calculate the total price after considering

the sales promotion as advertised and the sales tax. The total price will be rounded to the nearest dollar,

without charging any extra cents (e.g., if the calculated total price is $580.5, the total price being

charged will be $580.00 only). (Bonus part: Try to think of some error-checking for user inputs.)

Sample Input & Output:

===========================

Welcome to the Sales System

===========================

Please enter sales tax in % : 5

Number of purchased shoes : 2

Retail Price for shoes 1 : $300

Retail Price for shoes 2 : $300

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

Less: Discount applied : $114.00

Total price before tax : $486.00

Total price after tax (5%) : $510.00
