Write a program to find the sum of all even numbers from 1 to n where

1.	Write a program to find the sum of all even numbers from 1 to n where the value of n is taken as input. [for example when n is 10 then the sum is 2+4+6+8+10 = 30] using only two variables
Answer» PROGRAM: n = INT(input("ENTER a number")) SUM = 0 for i in range (1,(n+1),1): if int(i % 2) == 0: sum = sum + i print("The sum is : ") print(sum) Output Enter a number10 The sum is : 30 Language Python 3 -----Hope this helps :)

Answer»

n = INT(input("ENTER a number"))

SUM = 0

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

if int(i % 2) == 0:

sum = sum + i

print("The sum is : ")

print(sum)

Enter a number10

The sum is :
