Question

Use the following Car structure declaration to answer questions \(28-30\). struct Car string make model: Int year: double cost: // Constructors \(\operatorname{Car}()\) { make \(=\) model \(=" " ;\) year \(=\cos t=0: 1\) } Car(string mk, string md. int yr, double c) { make \(=\) whe model \(=\) ind : year \(=y r ; \quad \cos t=c: 1\)} Write a loop that will step through the array you defined in question 29 , displaying the contents of each element.

Short answer

Question: Write a loop that iterates through an array of Car structs and displays the contents of each element, where a Car struct contains the make, model, year, and cost. Answer: To iterate through an array of Car structs and display the contents of each element, you can use a loop like this: ```cpp for (int i = 0; i < sizeof(carsArray) / sizeof(carsArray[0]); i++) { cout << "Car " << i + 1 << ":" << endl; cout << " Make: " << carsArray[i].make << endl; cout << " Model: " << carsArray[i].model << endl; cout << " Year: " << carsArray[i].year << endl; cout << " Cost: $" << carsArray[i].cost << endl; } ``` This loop iterates through the array and prints the make, model, year, and cost of each car in the array.

Step-by-step solution

Define Car Structure

Define the Car structure with the given variables: ```cpp struct Car { string make; string model; int year; double cost; }; ```

Create an Example Array

Use an example array (from question 29) of Car structs: ```cpp Car carsArray[] = { Car("Ford", "Mustang", 2015, 25000.00), Car("Toyota", "Camry", 2020, 24000.00), Car("Honda", "Civic", 2016, 18000.00), }; ```

Write a Loop

Write a loop that iterates through the array and displays the contents of each element: ```cpp for (int i = 0; i < sizeof(carsArray) / sizeof(carsArray[0]); i++) { cout << "Car " << i + 1 << ":" << endl; cout << " Make: " << carsArray[i].make << endl; cout << " Model: " << carsArray[i].model << endl; cout << " Year: " << carsArray[i].year << endl; cout << " Cost: $" << carsArray[i].cost << endl; } ``` This loop will display the contents of each element of the Car array called carsArray. Inside the loop, it prints the make, model, year, and cost of each car in the array.
