HOMEWORK #2

Date: 03/11/2006 Due date: 16/11/2006

Computers are playing an increasing role in education. Write a program that will help an elementary school student learn multiplication. Use rand to produce two positive one-digit integers. It should then type a question such as:

How much is 6 times 7 ?

The student then types the answer. Your program checks the student’s answer. If it is correct, print “Very good!” and then ask another multiplication question. If the answer is wrong, print “No. Please try again.” And then let the student try the same question again repeatedly until the student finally gets it right.

NOTES:

1) Please make sure that each time your program is run, your algorithm should generate different random numbers.

2) Use sentinel value to exit from reading integer numbers.

3) Use a function to do multiplication.

Recommendations & Cautions:

1) Write the purpose of the program at the beginning of your code using the comment sign.

2) Provide the necessary explanations for the variables you use.

3) Explain which program you used for the source code generation (MS Visual C++, .NET or GNU C Compiler) for the proper evaluation of your homework. Give this information in your e-mail.

4) Homeworks submitted after the due date will not be accepted.

5) Submit your homework through the web page.

Good Luck!
