______________

The Problem.

You will write a program to determine the gas mileage for a trip given the miles driven and the gallons consumed.  The program should then calculate and print out the miles per gallon.  Lastly, the program will print a comment based on the MPG results.  

    * Develop your solution in a file named LabExam1.c there on vogon.

    * Store the miles driven and gallons used as integers.

    * Calculate the miles per gallon with two places after the decimal;

    * Use the following as comments based on the miles per gallon:

mpg >= 30             Tree hugging is the best.

30 > mpg >= 22     You've seen Inconvenient Truth.

22 > mpg >= 15     What's Global Warming??

15 > mpg                I think you just ran over Bambi with your Hummer.

    * Your prompts and output must match mine exactly.

    * You do not need to put any comments in your code.

    * You must compile on Vogon with the –Wall –ansi –pedantic flags with no warnings or errors.

Sample Runs:

Enter the miles driven: 300

Enter the number of gallons used: 8

Your MPG is: 37.50

Tree hugging is fun.

Enter the miles driven: 300

Enter the amount of gallons used: 25

Your MPG is: 12.00

I think you just ran over Bambi with your Hummer.
