C++核心准则ES.60:避免在资源管理函数之外使用new和delete

ES.60: Avoid new and delete outside resource management functions

ES.60:避免在资源管理函数之外使用new和delete

Reason（原因）

Direct resource management in application code is error-prone and tedious.

在应用代码中直接进行资源管理麻烦且易错。

Note（注意）

This is also known as the rule of "No naked new!"

本准则也被称为“禁止暴露的new操作”

Example, bad（反面示例）

void f(int n)
{
    auto p = new X[n];   // n default constructed Xs
    // ...
    delete[] p;
}

There can be code in the ... part that causes the delete never to happen.

在...省略的位置的代码可以让delete操作永远不发生。
