Program Plan Intro

Nth Fibonacci number

Program Plan:

  • Define the main function.
    • Get the value of “n” from the user.
    • Declare required variables “f1”, and “f2”.
    • Loop from 1 through “n”.
      • Calculate the value of “f3”.
      • Check if the value of “i” is equal to “n-1”.
        • Print the value of “f3”.
      • Assign the value of “f2” to “f1”.
      • Assign the value of “f3” to “f2”.

A Fibonacci sequence is a sequence of numbers where each successivenumber is the sum of the previous two. The classic Fibonacci sequencebegins: 1, 1, 2, 3, 5, 8, 13, .... Write a program that computes the nthFibonacci number where n is a value input by the user. For example, ifn = 6, then the result is 8.
A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is Area = ( n * s2 ) / (4 * tan( π/n) Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area.
This example creates a program to teach a first grade child how to learn subtractions. The program randomly generates two single- digit integers number1 and number2 with number1 > number2 and displays a question such as "What is 9 – 2?" to the student. After the student types the answer, the program displays a message to indicate whether the answer is correct.
