如何在 C++ 中简洁地初始化安全集合？
我现在正在学习 C++，我正在寻找一种方法来快速轻松地初始化每个元素具有不同值的“安全”集合（如向量）。我习惯了 Python 简洁的列表/元组初始化，并且我想知道 C++ 中是否有等效的语法技巧或集合类型。
例如，如果我想在 Python 中初始化唯一 Payment 对象的列表，我可以这样做：
payments = [Payment(10, 2), Payment(20, 4), Payment(30, 6)]
但是，为了在 C++ 中初始化 Payment 结构向量，我需要编写如下内容：
Payment tempPayments[] = {
{10, 2},
{20, 4},
{30, 6}
};
vector<Payment> examplePayments(tempPayments, tempPayments +
sizeof(tempPayments) / sizeof(Payment));
有没有更简单的方法初始化具有独特结构的向量，还是其他更方便的安全集合？

C++: Easiest way to initialize an STL vector with hardcoded elements
I'm learning C++ right now, and I'm looking for a way to quickly and easily initialize a "safe" collection (like a vector) with different values for each element. I'm accustomed to Python's concise list/tuple initializations, and I want to know if there's an equivalent syntax trick or collection type in C++.
For example, if I want to initialize a list of unique Payment objects in Python, I can do this:
payments = [Payment(10, 2), Payment(20, 4), Payment(30, 6)]
However, in order to initialize a vector of Payment structures in C++, I need to write something like this:
Payment tempPayments[] = {
{10, 2},
{20, 4},
{30, 6}
};
vector<Payment> examplePayments(tempPayments, tempPayments +
sizeof(tempPayments) / sizeof(Payment));
Is there an easier way to initialize a vector with unique structures, or another safe collection that's more convenient?

查看Boost.Assign，特别是< a href="http://www.boost.org/doc/libs/1_42_0/libs/assign/doc/index.html#list_of" rel="nofollow noreferrer">list_of。它允许您使用以下代码初始化集合：
Look into Boost.Assign, particularly list_of. It allows you to initialize a collection using code such as:
