Week 3 : Types, classes and interfaces

Pre-requisites:

• Went through preparation

Lesson Plan:

1. Questions from preparation and homework from week 2
2. Let's go over the preparation materials
3. Exercises!

Exercises

1. Create a class named Temperature and make a constructor with one decimal parameter - degrees (Celsius) and assign its value to Property. The property has a public getter and private setter. The property setter throws an exception if temperature is less than 273.15 Celsius. Then, create a property Fahrenheit that will convert Celsius to Fahrenheit (it has no setter similar to NicePrintout)

Bonus: create Kelvin property

var temperature = new Temperature(10);
Console.WriteLine($"{temperature.Celsius} Celsius is {temperature.Fahrenheit} Fahrenheit");

2. Create a class named ExchangeRate with a constructor with two string parameters, fromCurrency and toCurrency. Add a decimal property called Rate and method Calculate with decimal parameter amount return value of the method should be a product of Rate and amount multiplication.

Bonus: We should also check that Rate or amount are not negative.

var amount = 100;
var exchangeRate = new ExchangeRate("EUR", "DKK");
exchangeRate.Rate = 7.5m;
Console.WriteLine($"{amount} {exchangeRate.FromCurrency} is {exchangeRate.Calculate(amount)} {exchangeRate.ToCurrency}");
