challenge

Your challenge is this: make a protocol that describes a building, adding various properties and methods, then create two structs, House and Office, that conform to it. Your protocol should require the following:

1. A property storing how many rooms it has.
2. A property storing the cost as an integer (e.g. 500,000 for a building costing $500,000.)
3. A property storing the name of the estate agent responsible for selling the building.
4. A method for printing the sales summary of the building, describing what it is along with its other properties.

solution

protocol Building {
    var name: String { get set }
    var rooms: Int { get set }
    var cost: Int { get set }
    var estateAgent: String { get set }
    func printSummary()
}

extension Building {
    func printSummary() {
        let summary = """
\(name):
- has \(rooms) rooms.
- costs \(cost).
- \(estateAgent) is responsible for selling here.

"""
        print(summary)
    }
}

struct House: Building {
    var name: String
    var rooms: Int
    var cost: Int
    var estateAgent: String
}

struct Office: Building {
    var name: String
    var rooms: Int
    var cost: Int
    var estateAgent: String
}

var greenHouse = House(name: "green house", rooms: 3, cost: 100_000, estateAgent: "Ms. Green")
var smallOffice = Office(name: "small office", rooms: 2, cost: 1_000_000, estateAgent: "Some Boss")
greenHouse.printSummary()
smallOffice.printSummary()

결과:

green house:
- has 3 rooms.
- costs 100000.
- Ms. Green is responsible for selling here.

small office:
- has 2 rooms.
- costs 1000000.
- Some Boss is responsible for selling here.
