Exercise 2.5

Write a complete program that calculates  the product of three integers. 
The program should do each of the following: 
a) State that a program will calculate the product of three integers.
b) Define the variables x, y, z and result to be of type int. 
c) Prompt the user to enter three integers. 
d) Read three integers from the keyboard and store them in the
variables x, y and z. 
e) Compute the product of the three integers contained in variables x, y
and z, and assign the result to the variable result.
f) Print "The product is" followed by the value of the integer variable result.

Exercise 2.16

Write a program that asks the user to enter two numbers, obtains the two
numbers from the user and prints the sum, product, difference, quotient
and remainder of the two numbers. 

Exercise 2.18

Write a program that asks the user to enter two integers, obtains the
numbers from the user, then prints the larger number followed by the
words "is larger." If the numbers are equal, print the message "These
numbers are equal."

Exercise 2.24

Write a program that reads an integer and determines and prints whether
it is odd or even. [Hint: Use the remainder operator. An even number is a
multiple of two. Any multiple of two leaves a remainder of zero when
divided by 2.]

Exercise 2.26

Write a program that reads in two integers and determines and prints if
the first is a multiple  of the second. [Hint: Use the remainder
operator.]

Exercise 2.29

Here's a peek ahead. In this chapter you learned about integers and
the type int. C can also represent uppercase letters, lowercase
letters and a considerable variety of special symbols. C uses small
integers internally to represent each different character. The set of
characters a computer uses together with the corresponding integer
representations for those characters is called that computer's
character set. You can print the integer equivalent of uppercase A,
for example, by executing the statement

           printf( "%d", 'A' );

Write a C program that prints the integer equivalents of some
uppercase letters, lowercase letters, digits and special symbols. As a
minimum, determine the integer equivalents of the following:
    A B C a b c 0 1 2 $ * + / and the blank character.

Exercise 2.30

Write a program that inputs one five-digit number, separates the
number into its individual digits and prints the digits separated from
one another by three spaces each. [Hint: Use combinations of integer
division and the remainder operation.] For example, if the user types in
42139, the  program should print
   4   2   1   3   9
