Question

- Discuss the input-process-output model as it relates to program development.

Answer 1

• This is called IPO cycle.
• IPO stands for Input Process Output.
• All parts are necessary .

Lets see example.

Look at the program created in python below.

$\tt num=int(input("Enter\:a\: number:"))$

$\tt for\:i\:in\:range(3):$

$\qquad\tt print(i*x)$

Suppose you missed the input or don't give that then you won't get an output.
