Practice Problems

Below are three quick problems to help you apply what you learned. Create a new document for each problem so you can practice building from scratch.

Problem 1: Simple Addition

Objective: Create pseudocode that adds two numbers provided by the user.

Instructions:

Write Pseudocode:
- Outline the steps to prompt the user for two numbers, add them, and display the result.
Example Output:

yaml
Copy
Enter the first number: 5
Enter the second number: 7
The sum of the two numbers is: 12

Problem 2: Greeting Message

Objective: Develop pseudocode that greets the user by their name.

Instructions:

Write Pseudocode:
- Outline the steps to prompt the user for their name and display a personalized greeting message.
Example Output:

mathematica
Copy
Enter your name: Alice
Hello, Alice! Welcome to JavaScript programming.

Problem 3: Temperature Conversion

Objective: Create pseudocode that converts temperature from Celsius to Fahrenheit.

Instructions:

Write Pseudocode:
- Outline the steps to prompt the user for a temperature in Celsius, convert it to Fahrenheit, and display the result.
Conversion Formula:
- F = (C * 9/5) + 32
Example Output:

mathematica
Copy
Enter temperature in Celsius: 25
25°C is equal to 77°F.

Problem 4: Scaling a Cake Recipe

Objective: Given a base recipe for one cake, write pseudocode to scale the ingredient amounts for n cakes.

Instructions:

Prompt the baker: “How many cakes do you need to make?” → store in cakeCount.
You have an array of ingredient amounts for one cake (e.g. flour: 2 cups, sugar: 1.5 cups, eggs: 3).
Loop through each ingredient, multiply its amount by cakeCount, and store the result.
At the end, output a list of scaled ingredient amounts, e.g.:

yaml
Copy code
For 4 cakes you need:
- Flour: 8 cups
- Sugar: 6 cups
- Eggs: 12

Problem 5: Batch Baking Scheduler

Objective: Write pseudocode to plan a bake schedule for a given number of batches, including mixing and baking steps.

Instructions:

Prompt the baker: “How many batches will you bake?” → store in batchCount.
For each batch from 1 to batchCount:
- Print “Batch i: Mix ingredients.”
- Print “Batch i: Preheat oven to 350°F and bake for 30 minutes.”
- Print “Batch i: Let cool for 15 minutes.”
After the loop, print “All batches are complete!”

Problem 6: Ingredient Inventory Checker

Objective: Given an array of ingredient stock levels, write pseudocode to identify any low-stock items and alert the baker.

Instructions:

You have a list of ingredients, each with a current quantity (e.g. [{name: "flour", qty: 3}, {name: "sugar", qty: 0.5}, …]).
Define a minimum threshold (e.g. 1 cup or 1 unit).
Loop through each ingredient:
- If its qty is below the threshold, add its name to a lowStock list.
After checking all, if lowStock is not empty, print:

yaml
Copy code
Please reorder: flour, sugar, …

Otherwise, print “All ingredients in stock.”

Problem 7: Batch Temperature Converter

Objective: Write pseudocode to convert a series of oven temperature readings from Celsius to Fahrenheit.

Instructions to Students:

Start the conversion process.
Ask the baker: “How many temperature readings do you have?” → store in readingCount.
Initialize an empty list fahrenheitTemps.
Loop from 1 to readingCount:
- Prompt: “Enter temperature #i in Celsius.” → store in celsius.
- Convert: fahrenheit = (celsius * 9/5) + 32.
- Add fahrenheit to fahrenheitTemps.
After the loop, output:

sql
Copy code
Converted temperatures (°F):
[all values from fahrenheitTemps]

End the process.
