Input Format
There are  lines of numeric input:
The first line has a double,  (the cost of the meal before tax and tip).
The second line has an integer,  (the percentage of  being added as tip).
The third line has an integer,  (the percentage of  being added as tax).
Output Format
Print the total meal cost, where  is the rounded integer result of the entire bill ( with added tax and tip).

Problem solution in the Swift programming language.

import Foundation

// Calculate Tax and Tip doubles:
let tip = mealCost * tipPercent / 100;
let tax = mealCost * taxPercent / 100;

// cast the result of the rounding operation to an int and save it as totalCost 
let totalCost = Int(round(mealCost + tax + tip));

print("The total meal cost is \(totalCost) dollars.");
