Functions with pointers in C -- 2

Design (using a flowchart and pseuodocode) and implement an modular program that will allow users to repeatedly purchase fuel. In the program, call a function that will prompt the user for the fuel type (Regular, Premium, Supreme, Deisel, or None) and return the selection. (Read the respective fuel prices per gallon from the file fuelPrices.txt.) Call a function that will allow the user to choose the car wash (5.00) and return the selection. Call a function that will allow the user to enter the number of gallons of fuel or the total due. If the user chooses to enter gallons, compute the fuel total, car wash amount, and total due. If the user enters the total due, compute the car wash amount, the total due, and the gallons. Upon returning from the function, display the type of fuel, fuel price per gallon, number of gallons, fuel total, car wash amount, and total due. Fuel Prices:R 3.45-P 3.65-S 3.85-D 4.05
