PROGRAMMING ASSIGNMENT #2 

Write a C program that determines the miles per gallon for 3 tanks of gasoline that a user fills in his/her car. 

We will explain to the user very clearly what the program will be doing and how they should enter data. 

The program should prompt the user to enter the number of gallons used and the number of miles driven for each of the 3 tanks of gas. The program should then calculate and display the miles per gallon obtained for each tank. Once processing is complete for the 3 tanks, the program will calculate the overall mileage(total gallons / total miles) and display a friendly "Goodbye" message as shown below. 

Once you create, compile, link and run your program, your program should present the following dialog to the user: 

Welcome to the mileage calculator. 

This program will calculate the miles per gallon for you for three tanks of gas after you have entered the gallons used and miles driven. 

Enter the number of gallons used for tank #1: 12.8 Enter the number of miles driven: 287.1 *** The miles per gallon for this tank is 22.4 

Enter the number of gallons used for tank #2: 10.3 Enter the number of miles driven: 200.2 *** The miles per gallon for this tank is 19.4 

Enter the number of gallons used for tank #3: 5.2 Enter the number of miles driven: 120.9 *** The miles per gallon for this tank is 23.3 

Your overall average miles per gallon for three tanks is 21.5 

Thank you for using the program. Goodbye. 

 Hints:  In this program you may use 1 variable of type int, and 5 or 6 of type float.  

This program requires an introductory statement to the user.  

This program requires a loop structure (a for loop is best, or while or do — your choice). 

Note that the loop in the input flushing code (to clear input buffer) does not count. 

 The loop requires 3 printf statements as described here: 

o a printf statement to prompt the user for the "number of miles driven" 

o a printf statement to prompt the user for the "number of gallons used" 

o a printf statement to display the calculated "miles per gallon for this tank".  

The loop also requires 2 scanf statements as described here:

 o a scanf statement to "read in" the number of gallons used which is input by the user. 

o a scanf statement to "read in" the number of miles driven, which is also input by the user.  

This program requires 3 calculations within the loop as described here: o one calculation to determine for the "total miles per gallon " 

o one accumulator to keep track of (add up) the total miles driven (used for the final calculation). 

o one accumulator to keep track of (add up) the total gallons used (used for the final calculation).  

This program requires another printf statement (outside the for loop) to display the average miles per gallon for all tanks. 

 The loop index can be used to display the current tank calculation.
