Sum of first n natural numbers

Program Plan:

  • Define the main function.
    • Get the value of “n” from the user.
    • Declare a variable “sum” and assign 0 to it.
    • Loop from 0 through n.
      • Calculate the value of sum and store it in a variable “sum”.

Write a program that calculates the sum of all positive integers less than or equal to a given number N.
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.
Code in Python   Write a program to find the 6-th Monisen number. Classic Programming Question: find the n-th Monisen number. A number M is a Monisen number if M=2**P-1 and both M and P are prime numbers. For example, if P=5, M=2**P-1=31, 5 and 31 are both prime numbers, so 31 is a Monisen number. Put the 6-th Monisen number into a single text file and submit online
