basic over view>> banks offer car loans for periods ranging from two to five years (24 to 60 months). Write a program to allow the customer to enter the price of a car, the down payment amount and the annual interest rate of the loan. The program should display the loanâ€™s duration in months and the monthly payments for two-, three-, four-, and five- year loans. The output should be displayed in fixed-point notation, rounded to two decimal places of precision. payment =(rate*(pow(1 + rate),n) / ((pow(1 +rate),n)- 1)) * L. Rate is the monthly interest rate, N is the number of payments and L is the amount of the loan.

PROBLEM>>i'm getting: uninitialized local variable 'loanDuration' used. in what way can i fix this?
