C++核心準(zhǔn)則ES.60:避免在資源管理函數(shù)之外使用new和delete

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

ES.60:避免在資源管理函數(shù)之外使用new和delete

Reason（原因）

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

在應(yīng)用代碼中直接進(jìn)行資源管理麻煩且易錯(cuò)。

Note（注意）

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

本準(zhǔn)則也被稱為“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...省略的位置的代碼可以讓delete操作永遠(yuǎn)不發(fā)生。

Enforcement（實(shí)施建議）

Flag naked?news and naked?deletes.

標(biāo)記暴露的new和delete操作。
