A bank has the following rule: if a customer has more than $1000 dollars in their checking account or more than $1500 dollars in their savings account, then there is no service charge for writing checks. Otherwise there is a $0.15 charge per check. Write a program that asks for the balance in each account and then writes out the service charge.

The front tires of a car should both have the same pressure. Also, the rear tires of a car should both have the same pressure (but not necessarily the same pressure as the front tires.) Write a program that reads in the pressure of the four tires and writes a message that says if the inflation is OK or not.
Input right front pressure 38 Input left front pressure 38 Input right rear pressure 42 Input left rear pressure 42 Inflation is OK

Its not enough that the pressures are the same in the tires, but the pressures must also be within range. Modify the program in exercise 1 so that it also checks that each tire has a pressure between 35 and 45. If a tire is out of range, write out an error message immediately, but continue inputting values and processing them:
Input right front pressure 32 Warning: pressure is out of range Input left front pressure 32 Warning: pressure is out of range Input right rear pressure 42 Input left rear pressure 42 Inflation is BAD
If there have been any warnings, write out a final error message. (To do this, declare a boolean variable goodPressure that is initialized to true but is changed to false when an out of range tire is first found.)

Tires don't have to have exactly the same pressure. Modify the program for exercise 2 so that the front tires can be within 3 psi of each other, and the rear tires can be within 3 psi of each other.
Input right front pressure 35 Input left front pressure 37 Input right rear pressure 41 Input left rear pressure 44 Inflation is OK
