一. 开发环境环境
- 基本环境设置
gcc -v 查看编译器版本
http://www.runoob.com/cplusplus/cpp-environment-setup.html - CMake 编译器/链接器
https://blog.csdn.net/xierhacker/article/details/79445339
cpplint ? - 基于VSCode
https://code.visualstudio.com/docs/languages/cpp
【C/C++】extension. This is an official Microsoft extension.
【CMake】extension.
【CMake Tools】extension. This enables usage of a set of CMake commands from inside VS Code.
【Native Debug】.
C++ libraries ？
.vscode
.cmaketools.json # CMake: Build
.c_cpp_properties.json # C/Cpp: Edit Configurations
.launch.json # Debug: Open launch.json 【C++ (GDB/LLDB)】

- 基于VIM？
二、基础

- Boost类库
https://futucocoa.github.io/2017-01-06-macOSBoostInstallGuide/
brew install boost
/usr/local/Cellar/boost/1.67.0_1
boost::lexical_cast 2
boost::split 1
boost::shared_ptr 1
boost::is_any_of 1
boost::static_pointer_cast 1
boost::random::mt 1
boost::random::discrete_distribution 1 -
Google Protocol Buffers
https://developers.google.com/protocol-buffers/
https://www.ibm.com/developerworks/cn/linux/l-cn-gpb/index.html
which protobuf
conda install protobuf
protoc --version
cmake+pb
三、应用
https://github.com/fffaraz/awesome-cpp
- 日志库
- 配置文件？
- 读写redis
- 读写mysql
- http/rpc请求
- pb/json/xml处理？
四、高级
GDB
出core后如何调试
内存泄露，cpu狂涨的原因追查
五、优秀的开源项目
sqlite
redis
nginx
六、其他
union,联合体？
make -j 8 #多线程编译
符号：
::
<<
->
&
.
标识符：
https://www.runoob.com/w3cnote/cpp-keyword-intro.html
auto，声明变量时根据初始化表达式自动推断该变量的类型、声明函数时函数返回值的占位符
static，在程序的生命周期内保持局部变量的存在，而不需要在每次它进入和离开作用域时进行创建和销毁
const_cast
dynamic_cast
static_cast
reinterpret_cast
delete
explicit
export
extern
friend
mutable
operator
register，用于定义存储在寄存器中而不是 RAM 中的局部变量
template
this
typedef #为一个已有的类型取一个新的名字
typeid
typename
union
virtual
volatile
wchar_t
三字符组， 不常见？
数据结构？
std::vector<uint64_t>
std::map<uint64_t, int>
std::unordered_map<uint64_t, int64_t>
std::pair<std::string, float>
std::max
std::rand()
std::shared_ptr
std::accumulate
boost::random::discrete_distribution<>
boost::random::mt19937 gen((unsigned int) std::time(NULL));
boost::split
boost::is_any_of(",")
boost::lexical_cast<uint64_t>
std::make_pair
c++指针
引用
三、常用类库
std::unordered_map
std::shared_ptr
std::string
c++ 使用pb?
多线程编程？
操作pb？
四、常见问题？
1.# error passing 'const' as 'this' argument
简单语法了解
常用类库
virtual, 接口定义？Base的虚拟函数，子类可以重写虚拟函数。
typedef,
类型转换：str 转int 等
