I need help writing a progrm in C++ using arrays.

You are to write a program which inputs the base price of a car. Then, the program will input in a 2-letter code (a string) which corresponds to an option package. All the 2 letter codes will be in an array (string), along with the corresponding cost of the package in a parallel array (doubles), and there is also another array with the name of the package (string).

Your program first has to determine if the 2-letter code input by the user is valid. You are required to use a loop to check the input against each item in the optionPackageCodeArray. Begin with the first item then "walk" down through the array. If the code does NOT exist on the list, display an error message and stop. If the code is valid, do some calculation and displaying. First, add the base price to the package cost from the array and get a subtotal. Then, calculate 15% of the subtotal for taxes and fees and add that to the subtotal for a final price. Display the final price and the full name of the package from the last array, then stop. Here is the data for the 3 parallel arrays:

OptionPackageCodeArray		PackageCostArray		PackageNameArray
BB		1500.00		Base
SP		3250.00		Sport
NP		4575.00		Intermediate level
HE		7500.00		Luxury
UC		5220.00		User specified
