HAVE READ:

• pp. [96-103]

KNOW:

• if statement structure
• The existence of the java.lang.Math class
• The structure of computations: Sequential, Conditional
• Know difference between (&&, ||) and (&, |)

BE ABLE TO:

• Write programs with conditional control flow, based upon variable declarations

DAILY QUESTION:

• Write a program that defines an int variable x. Set x to some integer value of your choosing. Then define an if statement that will (a) output "Negative" if x is less than zero; (b) output "Zero" if x is equal to zero; (c) output "Positive" if x is greater than zero.

Sample Exam Question:

Given three int variables a, b, and c, show the series of if statements you would use to output these three values in ascending sorted order.

Go through all the steps in the design recipe in the development of your program.
