Example: Write a pseudocode and draw the flowchart to compute the factorial of a number.
Input:
num: the number whose factorial is required
Process:
Compute the product of numbers 1 to num.
Output:
Product as the factorial of given number
input num
product = 1
for i = 1 to num
product = product * i
end-for
Print product
The flowchart of the above pseudocode is as follows (Fig 4.12):
Start
input num
product = 1
i = 1
False
i< = num
True
product = product*i
i = i + 1
print product
Stop
