15. Write a pseudocode to calculate the factorial of a number ( Hint: Factorial of 5, written as 5! =5×4×3×2×1).
Ans. input num
product ← 1, i ← 1
while i <= num do
product ← product * i
i ← i + 1
end-while
print "factorial=", product
16. Draw a flowchart to check whether a given number is an Armstrong number. An Armstrong number of three digits is an integer such that
the sum of the cubes of its digits is equal to the number itself. For example, 371 is an Armstrong number since 3**3 + 7**3 + 1**3 = 371.
Ans.

Start

Input n

sum = 0
m = n

if False if False Print
n > 0 m = sum Not Armstrong
True

r = n % 10 Print
n = n / 10 Armstrong
sum = sum + r 3

Stop

17. Following is an algorithm to classify numbers as
"Single Digit", "Double Digit" or "Big".
Classify_Numbers_Algo
INPUT Number
IF Number < 9
"Single Digit"
Else If Number < 99
"Double Digit"
Else
"Big"
Verify for (5, 9, 47, 99, 100 200) and correct the algorithm if required
