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.

Pavlova-9 [17]

Answer:

In Python:

service = input("Enter desired auto service: ")

print("You entered: "+service)

if service.lower() == "oil change":

print("Cost of oil change: $35")

elif service.lower() == "car wash":

print("Cost of car wash: $7")

elif service.lower() == "tire rotation":

print("Cost of tire rotation: $19")

else:

print("Invalid Service")

Explanation:

First, we prompt the user for the auto service

service = input("Enter desired auto service: ")

Next, we print the service entered

print("You entered: "+service)

Next, we check if the service entered is available (irrespective of the sentence case used for input). If yes, the cost of the service is printed.

This is achieved using the following if conditions

For Oil Change

if service.lower() == "oil change":

print("Cost of oil change: $35")

For Car wash

elif service.lower() == "car wash":

print("Cost of car wash: $7")

For Tire rotation

elif service.lower() == "tire rotation":

print("Cost of tire rotation: $19")

Any service different from the above three, is invalid

else:

print("Invalid Service")
