The use of computers in education is  referred to as "Computer
Assisted Instruction" (CAI). One problem that develops in CAI
environments is student fatigue. This can be eliminated by varying the
computer's dialogue to hold the student's attention.
Write a program to drill multiplication facts: the program should
produce two positive one-digit integers aand the type a question such
as:

How much is 6 times 7?

The student then types an answer. Your program should then provide a
response that is randomly generated based on the students response:
if the answer is correct, the response could be something like:
Correct!
Good job!
Excellent!
NIce work!
and if the answer is incorrect, the response could be something like:
No, please try again.
Wrong, please try once more
Aw dear, that wasn't it. Let's try again.
Don't give up!

Your program should have at least five random phrases for each case.
Use a switch statement to print out the one you need, chosen with a
call to a random number generator.
