Using C

Write a program that determines the Fibonacci number for the nth term. Recall, the first Fibonacci number is 0 and the second Fibonacci number is 1. The next number in the sequence is always determined by the sum of the previous two terms or numbers in the sequence. Fib (n) = Fib (n-1) + Fib (n-2). The n value should be entered by the user. Use functions where appropriate!
