COMP 218 Fundamentals of Object-Oriented
Programming
Assignment 1

Please note: you are NOT allowed to post the assignment/solution anywhere on the
Internet. Intellectual Property rights are reserved. If any similar cases are found via your
account or IP, your submission will NOT be considered and will be reported
immediately.

General Guidelines when Writing Programs:
- Include the following comments at the top of your source codes
// -----------------------------------------------------
// Assignment (include number)
// Question: (include number)
// File name: (include source code file name)
// Written by: (include your name and student id)
// -----------------------------------------------------
- In a comment, give a general explanation of what your program does. As the
programing questions get more complex, the explanations will get lengthier.
- Include comments in your program describing the main steps in your program.
- Print a welcome message which includes your name.
- Display clear prompts for users when you are expecting the user to enter data
from the keyboard.
- All output should be printed out with clear messages and in an easy to read
format.
- End your program with a closing message so that the user knows that the
program has terminated.

Question #1: Display a message (3 pts)
Write a complete C++ program that displays the following output exactly as in the
sample output. You are to use a single cout statement to output the message. There is
no need to declare any variables for this question.

Question #2: Number Generator Program (6 pts)
In C++, we can use rand() function (More details) to generate random numbers. In the
number calculation following the requirements:
1. Display a welcome message.
2. Display the randomly generated even/odd number.

Figure 2 – Sample output #1 for Question 2
For example, if the number is 1234, change it to 4321.
For example, 1221 is a palindrome as it is the same if reversed.
For example, the largest digit is 9 and smallest is 1, in 3179.
Your program must display the same information and formatted the same.
3. Reverse the number.
4. Check if the number is a palindrome.
5. Find the smallest and largest digit in the number
question, we will generate a 4-digit random number between 1000 – 9999 and complete
Use at least one constant variable to store value in the program.
Following are 2 sample screen shots to illustrate the expected behavior of your
program.

Question #3: New Word Program (6 pts)

Your program should behave as follow:
1. Display a welcome message.
2. Ask the user to prompt 3 words with at least 1 letter.
3. Ask the user to prompt 3 numbers, that should be less than the length of each
word to indicate length of substring in each word. For example, if the word is
Ann, then the entered number should be less than 3 (the length of Ann).

5. Display the resulting new word.
6. Display a farewell message, so that the user knows that the program has
terminated normally.
Restriction: This questions requires the use of the functions: length(), substr().
Assumption: Assume a perfect user who will always enter the correct input values.

Following are two sample screen shots to illustrate the expected behavior of your
program. Your program is to work with any words entered by the user.

last n characters. Concatenate the three resulting substrings into a single
new word.
4. For each word, create a new substring by taking the first n characters and the

Submitting Assignment 1
- Naming convention for zip file to submit: Create one zip file, containing all source
files (.cpp files only) for your assignment. The zip file should be called
a#_studentID, where # is the number of the assignment and studentID is your
student ID number. For example, for the first assignment, student 123456 would
submit a zip file named a1_123456.zip. (See instructions on how to zip files
which are posted in the Assessment section of the eConcordia course webpage.)
- Submit only ONE version of an assignment.
- Late assignments will be discounted by 25%. Late assignments are accepted up
to five days late (grace period) and weekends count.
