c) To display the multiplication table of a given number.

d) To display the sum of the first 30 natural numbers.

e) To display a message “hello” 20 times on the screen.​

Explanation:

1. start, end = 5, 20

# iteration

for num in range(start, end + 1):

  # check

  if num % 2 == 0:

     print(num, end = " ")

2. sum=0

for n in range(1,30):

  if n%2!=0:

     while n!=0:

        digit=n%10

        sum=sum*10+digit

        n=n//10  

     print(sum)

3.     number = int(input ("Enter the number of which the user wants to print the multiplication table: "))

   count = 1.

   # we are using while loop for iterating the multiplication 10 times.

   print ("The Multiplication Table of: ", number)

   while count <= 10:

   number = number * 1.

   print (number, 'x', i, '=', number * count)

4.  num = 30

if num < 0:

  print("Enter a positive number")

else:

  sum = 0

  # use while loop to iterate until zero

  while(num > 0):

      sum += num

      num -= 1

  print("The sum is", sum)

5. for I in 1 .. 20 loop

 Put_Line ("Hello");

end loop;
