// Exercise 6: Stripping Names: Store a person’s name, and include some whitespace characters at the beginning and end of the name. Make sure you use each character combination, "\t" and "\n", at least once. Print the name once, so the whitespace around the name is displayed. Then print the name after striping the white spaces.

//Exercise 10:Adding Comments: Choose two of the programs you’ve written, and add at least one comment to each. If you don’t have anything specific to write because your programs are too simple at this point, just add your name and the current date at the top of each program file. Then write one sentence describing what the program does.

let Name: string = "Tehreem"; // here i am doing store name in a variable.

//Exercise 44:Sandwiches: Write a function that accepts a array of items a person wants on a sandwich. The function should have one parameter that collects as many items as the function call provides, and it should print a summary of the sandwich that is being ordered. Call the function three times, using a different number of arguments each time.

function make_sandwich(...items: string[]) {
  console.log("sandwich Order");
  for (let i = 0; i < items.length; i++) {
    console.log(`-${items[i]}`);
  }
  console.log("enjoy your sandwiches");
}

make_sandwich("Turkey", "Lettuce", "Tomato", "Mayonnaise");
make_sandwich("Ham", "Cheese");
make_sandwich("Peanut Butter");

//Exercise 45:

// Define an interface for the Car object
interface Car {
  manufacturer: string;
  model: string;
  options: { [key: string]: any }; // Options can have arbitrary keys and values
}
// Define the make_car function
function make_car(
  manufacturer: string,
  model: string,
  ...options: { [key: string]: any }[]
): Car {
  // Initialize a car object
  const car: Car = {
    manufacturer,
    model,
   ...Object.assign({},...options)
  };
 
  return car;
}
const car = make_car("Toyota", "Corolla", { color: "blue" }, { sunroof: true });
