# Program to add natural
# numbers upto
# sum = 1+2+3+...+n
# To take input from the user,
# n = int(input("Enter n: "))
1.n = 10
# initialize sum and counter
2.sum = 0
3.i = 1
4.while i <= n:
5. sum = sum + i
6. i = i+1 # update counter
# print the sum
7.print("The sum is", sum)
When you run this code output will be:
