C++核心准则讨论：析构，释放和交换操作必须永不失败

Never allow an error to be reported from a destructor, a resource deallocation function (e.g., operator delete), or a swap function using throw. It is nearly impossible to write useful code if these operations can fail, and even if something does go wrong it nearly never makes any sense to retry. Specifically, types whose destructors might throw an exception are flatly forbidden from use with the C++ Standard Library. Most destructors are now implicitly noexcept by default.

C++核心准则：注释风格

C++核心准则GSL.view：视图

linux 编程算法

These types allow the user to distinguish between owning and non-owning pointers and between pointers to a single object and pointers to the first element of a sequence.

C++核心准则NR.1：不要坚持所有声明都应该放在函数顶部

编程算法 ide linux

The "all declarations on top" rule is a legacy of old programming languages that didn't allow initialization of variables and constants after a statement. This leads to longer programs and more errors caused by uninitialized and wrongly initialized variables.

C++核心准则Pro.safety：类型安全准则群组

This profile makes it easier to construct code that uses types correctly and avoids inadvertent type punning. It does so by focusing on removing the primary sources of type violations, including unsafe uses of casts and unions.

C++核心准则SL.str.3：使用zstring或czstring引用C风格0结尾的字符串序列

c++编程算法 linux

Readability. Statement of intent. A plain char* can be a pointer to a single character, a pointer to an array of characters, a pointer to a C-style (zero-terminated) string, or even to a small integer. Distinguishing these alternatives prevents misunderstandings and bugs.

C++核心准则SL.con.1:标准库array或vector好于C数组

编程算法 c++linux

C arrays are less safe, and have no advantages over array and vector. For a fixed-length array, use std::array, which does not degenerate to a pointer when passed to a function and does know its size. Also, like a built-in array, a stack-allocated std::array keeps its elements on the stack. For a variable-length array, use std::vector, which additionally can change its size and handles memory allocation.

C++核心准则Con.2:默认情况下，将成员函数定义为const类型

linux access 编程算法

A member function should be marked const unless it changes the object's observable state. This gives a more precise statement of design intent, better readability, more errors caught by the compiler, and sometimes more optimization opportunities.
