Question

Write a Program using any Programming language that takes a number from user (n) and execute 3 methods..
1: sum of Numbers from 1 to n
2: product of n to 1
3: average of sum from 1 to n
​

Answer 1

The following co‎des have been written using Python.

#obtaining the number from the user

n = int(input("Enter a number: "))

#calculating the sum

s = 0

for i in range(1, n + 1):

   s = s + i

print(s, "is the sum of the numbers from 1 to", str(n) + ".")

#calculating the product

p = 1

for i in range(n, 0, -1):

   p = p*i

print(p, "is the product of the numbers from", n, "to 1.")

#calculating the average

l = list()

for i in range(1, n + 1):

   l.append(i)

avg = sum(l)/len(l)

print(avg, "is the average of the numbers from 1 to", str(n) + ".")
