Description
1. Write a program that reports whether a number input is divisible by 7.
Hint: If a number is divisible by 7, that means you can divide it by 7 and get a remainder
of 0.
Test Data:
(i)
Enter an integer number : 79
Your integer number: 79 is not divisible by 7
(ii)
Enter an integer number : 28
Your integer number: 28 is divisible by 7
2. Write a program that reads two integers from the keyboard and prints if the first is a multiple
of the second. Hint: Use modulus operator.
Test Data:
(i)
Enter the first integer : 23
Enter the second integer : 58
23 is NOT evenly divisible by 58
(ii)
Enter the first integer : 240
Enter the second integer : 3
240 is evenly divisible by 3

5. Write a program that reads in the quiz scores of a class of ten students. The grades are
integers in the range of 0-100. If the grade entered is not within this range, reject and ask
for a number in the range. Calculate and display the total of all student grades and calculate
the average.
Extra Credit (10%): Calculate the standard deviation. Use only what we have so far learned
in class about c++. YOu may need to do some lookup for standard deviation.

6. Write a program that displays the following menu:
Geometry Calculator
1. Calculate the Area of a Circle
2. Calculate the Area of a Rectangle
3. Calculate the Area of a Triangle
4. Quit
Enter your choice (1-4):
If the user enters 1, the program should ask for the radius of the circle and then display its
area. Use 3.14159 for π. If the user enters 2, the program should ask for the length and width
of the rectangle, and then display the rectangle’s area. If the user enters 3, the program
should ask for the length of the triangle’s base and its height, and then display its area. If
the user enters 4, the program should end. Input Validation: Display an error message if the
user enters a number outside the range of 1 through 4 when selecting an item from the menu.
Do not accept negative values for the circle’s radius, the rectangle’s length or width, or the
triangle’s base or height.

Deliverables:
1. Source Code: (.cpp file) that must start with a comment block similar to the following:
/*************************************************************************
** Author : Suleyman Uludag
** Program : hw1, q1
** Date Created : September 15, 2013
** Date Last Modified : September 16, 2013
** Usage : No command line arguments
**
** Problem:
Accept the following information from the user (keyboard):
– Hw1, hw2 and hw3 (out of 100)
– Midterm (out of 100)
– Final exam (out of 100)
Calculate the total grade out of 100 based on the following grading scale:
Hws –> 30% (10% each)
Midterm –> 30%
Final Exam –> 40%
** Pseudocode:
** 1)
** 2)
*************************************************************************/
2. Executable (.exe file under windows). You must explicitly state the platform of your executable (such as Linux, etc.) if it is not Windows. Please name your file by using the
question number: hw1-q1.exe (for Windows)
3. Screenshot of your app. For screenshot, you can use the following free program on windows:
http://www.wisdom-soft.com/downloads/setupscreenhunterfree.exe
For Linux/Unix, there are many alternatives. I personally like shutter.
File naming convention example:
hw1 q1.png (or .jpg or another graphics format)
4. You must zip all the above three files into ONE .zip file and submit your assignment by the
deadline on moodle system. Name your file as Lastname-Firstname-hw#.zip. For example,
Uludag-Suleyman-hw1.zip
For generating .zip file, you may use the following free software on Windows:
http://www.7-zip.org/download.html
Linux/Unix has many built-in.
