Create an array of objects and display details of N buildings along with the total cost

Sure, here is a step-by-step guide on how to create an array of objects and display details of N buildings along with the total cost. I'll use JavaScript for this example.

1. First, let's define a Building class:

class Building {
    constructor(name, cost) {
        this.name = name;
        this.cost = cost;
    }
}

2. Now, let's create an array of Building objects:

let buildings = [
    new Building('Building 1', 1000),
    new Building('Building 2', 2000),
    new Building('Building 3', 3000),
    // add more buildings as needed
];

3. To display the details of each building, we can use a loop:

for (let building of buildings) {
    console.log(`Name: ${building.name}, Cost: ${building.cost}`);
}

4. To calculate the total cost of all buildings, we can use the reduce method:

let totalCost = buildings.reduce((sum, building) => sum + building.cost, 0);
console.log(`Total cost: ${
