Shopping Cart V1 - Single Item Total in Swift

Practice

Practice variables, arithmetic, and string concatenation by printing a tiny one-item receipt.

You start with:

        let item = "Coffee Mug"
        let price = 12
        let quantity = 3

Build:

Coffee Mug x3
Total: $36

Rules:

Compute total = price * quantity.
First line: "<item> x<quantity>" (e.g. "Coffee Mug x3").
Second line: "Total: $<total>".
Join the two lines with a newline "\n" into one string result, then print it with print(result).

Swift's string interpolation \(...) embeds any value directly in a string literal.

line1 + "\n" + line2 joins both lines into one string.

        let item = "Coffee Mug"
        let price = 12
        let quantity = 3

        let total = price * quantity
        let line1 = "\(item) x\(quantity)"
        let line2 = "Total: $\(total)"
        let result = line1 + "\n" + line2
        print(result)
