如何在C++中创建可重复的对象列表？

Question

我开始从Python开始C++，所以我只是在浏览基本知识。当我试图创建一个包含对象的数组时，问题就出现了。在Python中，我将有一个具有color和year属性的类Car：

myCars = [Car("Red", 1986), Car("Black", 2007), Car("Blue", 1993)]
# and then going through the cars:
for car in myCars:
print("The car has the color " + car.color + " and is " + (2014 - car.year) + " years old.")

试图在C++中做类似的事情：

struct Car {
    string color;
    int year;
};

int cars[3] = {Car cars[0], Car cars[1], Car cars[2]}
//EDIT: I wrote bilar but I meant cars.

但对这些车进行迭代确实很无趣，首先，这不起作用，其次，它们没有任何属性。我只是不明白，我想也许我错过了一些重要的事情，把它都搞错了，但是，我想我应该把这个解释清楚。你知道吗

尝试这个（C++ 11）-看起来几乎像Python：

std::vector<Car> cars = {{"Red", 1986}, {"Black", 2007}, {"Blue", 1993}};
for (const Car& car : cars) {
    std::cout << "The car has the color " << car.color << " and is " 
        << (2014 - car.year) << " years old." << std::endl;
}

C++构建：

• ^{}
• list initialization
• range ^{} loop
