Question

Write an algorithm for a vending machine that sells just one product. The machine flashes a yellow light when the quantity inside is below 40% of capacity​

Answer 1

The algorithm is as follows:

1. Start

2. Capacity = 100%

3. Input Status (True/False)

4. While Status == True

4.1. Read Quantity (%)

4.2. Capacity = Capacity - Quantity

4.3. If Capacity < 40%

4.3.1 Display Yellow Flash

4.4. Input Status (True/False)

5. Stop

Step-by-step explanation:

This starts the algorithm

1. Start

The capacity of the machine is initialized to 100%

2. Capacity = 100%

This gets the status of the sales

3. Input Status (True/False)

The following iteration is repeated until the status is false

4. While Status == True

Read current sales quantity from the user

4.1. Read Quantity (%)

Remove the quantity from the capacity

4.2. Capacity = Capacity - Quantity

Check is capacity is below 40%

4.3. If Capacity < 40%

If yes, display yellow flashes

4.3.1 Display Yellow Flash

This gets the status of the sales

4.4. Input Status (True/False)

End algorithm

5. Stop
