Program to print all armstrong numbers between 1 to n.

Algorithm:
Step 1: Start
Step 2: Read limit of number, n

Step 3: Repeat steps 4-11 until num=n+1

Step 4: Assign sum=0

Step 5: Assign temp=num

Step 6: Repeat steps 7,8&9 until temp=0 reaches

Step 7: Compute digit=temp%10

Step 8: Compute sum=sum+(digit**3)

Step 9: Compute temp=temp/10

Step 10: if num==sum goto step 11

Step 11: Print num

Step 12: Stop

Flowchart:

Program code:

n=int(input('Enter the upper limit '))
for num in range (1,n+1):
    sum=0
    temp=num
    while temp>0:
        digit=temp%10
        sum=sum+(digit**3)
        temp=temp/10
    if num==sum:
        print num
