Fibonacci Number at a Given Position

This program calculates the Fibonacci number at a specified position in the sequence. The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, starting from 0 and 1. This program takes a position as input and outputs the Fibonacci number at that position.

Code Breakdown

Algorithm

  1. Start
  2. Input Position: Read the value of n (position) from the user.
  3. Check Position:
    • If n < 1, print "Invalid position" and exit.
  4. Initialize Variables:
    • Set a = 1, b = 0, and i = 0.
  5. Compute Fibonacci Number:
    • Loop until i is less than n:
      • Calculate c = a + b.
      • Update a to b.
      • Update b to c.
      • Increment i.
  6. Display Result:
    • Print the Fibonacci number at position n.
  7. End
