Program to print sum of all even numbers between 1 to n.

Algorithm:

Step 1: Start

Step 2: Read the limit of numbers, n

Step 3: Assign i=1

Step 4: Assign sum=0

Step 5: Repeat steps 6,7&8 until i=n reaches

Step 6: If i%2==0 goto step 7

Step 7: Compute sum=sum+i

Step 8: Compute i=i+1

Step 9: Print sum of even numbers, sum

Step 10: Stop

Flowchart:

Program code:

n=int(input('Enter the limit '))
i=1
sum=0
while i<n:
    if i%2==0:
        sum=sum+i
    i=i+1
print 'Sum of even numbers',sum
