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

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
Write a program that prompts the user for three words.

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.
