Example Output:

Algorithm RectangleAreaCalculator
    var length = Input "Enter length:"
    var width = Input "Enter width:"
    var area = length * width
    Print "The area of the rectangle is:", area
Endalgorithm

Problem:

Ask the user for their first name and last name, then combine them to display their full name.

Requirements:

• Get first name from user
• Get last name from user
• Combine them with a space in between
• Display the full name

Example Output:

Algorithm FullNameGenerator
    var firstName = Input "Enter first name:"
    var lastName = Input "Enter last name:"
    var fullName = firstName + " " + lastName
    Print "Your full name is:", fullName
Endalgorithm

Problem:

Convert a temperature from Celsius to Fahrenheit using the formula: F = C × 9/5 + 32

Example Output:

Algorithm CelsiusToFahrenheit
    var celsius = Input "Enter temperature in Celsius:"
    var fahrenheit = (celsius * 9 / 5) + 32
    Print celsius, "Celsius is", fahrenheit, "Fahrenheit"
Endalgorithm

Problem:

Calculate the total bill for two items, including a 10% sales tax.

Example Output:

Algorithm ShoppingBill
    var price1 = Input "Enter price of item 1:"
    var price2 = Input "Enter price of item 2:"
    var subtotal = price1 + price2
    var taxAmount = subtotal * 0.10
    var totalBill = subtotal + taxAmount
    Print "Subtotal:", subtotal
    Print "Tax (10%):", taxAmount
    Print "Total Bill:", totalBill
Endalgorithm

Problem:

Convert a given number of days into years, weeks, and remaining days (365 days/year, 7 days/week).

Example Output:

Algorithm TimeBreakdown
    var totalDays = Input "Enter total days:"
    
    var years = totalDays / 365
    var remainingDays = totalDays mod 365
    
    var weeks = remainingDays / 7
    var finalDays = remainingDays mod 7
    
    Print totalDays, "days is:"
    Print years, "Year"
    Print weeks, "Weeks"
    Print finalDays, "Days"
Endalgorithm

Problem:

Calculate the Body Mass Index (BMI) given weight in kilograms and height in meters. Formula: BMI = weight / (height × height)

Example Output:

Algorithm BMICalculator
    var weightKg = Input "Enter weight in kg:"
    var heightMeters = Input "Enter height in meters:"
    
    var bmi = weightKg / (heightMeters * heightMeters)
    Print "Your BMI is:", bmi
Endalgorithm

Problem:

Calculate both area and circumference of a circle given its radius (π = 3.14159).

Example Output:

Algorithm CircleProperties
    var pi = 3.14159
    var radius = Input "Enter radius:"
    
    var area = pi * radius * radius
    var circumference = 2 * pi * radius
    
    Print "Circle Area:", area
    Print "Circle Circumference:", circumference
Endalgorithm

Problem:

Convert USD to EUR, GBP, and JPY with proper formatting (1 USD = 0.85 EUR, 0.73 GBP, 110.50 JPY).

Example Output:

Algorithm CurrencyExchange
    var usdToEur = 0.85
    var usdToGbp = 0.73
    var usdToJpy = 110.50
    
    var usdAmount = Input "Enter amount in USD:"
    
    var eurAmount = usdAmount * usdToEur
    var gbpAmount = usdAmount * usdToGbp
    var jpyAmount = usdAmount * usdToJpy
    
    Print "$", usdAmount, "USD equals:"
    Print "€", eurAmount, "EUR"
    Print "£", gbpAmount, "GBP"
    Print "¥", jpyAmount, "JPY"
Endalgorithm

Problem:

Calculate a student's final grade average from 5 test scores and determine pass/fail status (average >= 60).

Example Output:

Algorithm StudentGradeAverage
    var test1 = Input "Enter test 1 score:"
    var test2 = Input "Enter test 2 score:"
    var test3 = Input "Enter test 3 score:"
    var test4 = Input "Enter test 4 score:"
