vector deque

在使用 vector、deque遍历删除元素时，也可以通过erase的返回值来获取下一个元素的位置：

std::vector<int> Vec;
std::vector<int>::iterator itVec;
for( itVec = Vec.begin(); itVec != Vec.end(); )
{
      if( WillDelete( *itVec) )
      {
           itVec = Vec.erase( itVec);
      }
      else
         itList++;
}

问题提出：有一个模板函数，函数在处理int型和double型时需要进行特殊的处理，那么怎么在编译期知道传入的参数的数据类型是int型还是double型呢？
如：

#include <iostream>
template <typename TYPE>
void typeCheck(TYPE data)
{
    //do something check data type
	//std::cout<< out put the type
}

这里就需要用到C++11的type_traits头文件了，type_traits头文件定义了很多类型检查相关的方法，上面的例子具体用到了其中两个结构：

1. Git 数据流转模型

理解 Git 的核心在于掌握数据在不同区域间的流转。

%%{init: {'theme': 'base', 'themeVariables': { 'primaryColor': '#4F46E5', 'primaryTextColor': '#fff', 'primaryBorderColor': '#3730A3', 'lineColor': '#6366F1', 'secondaryColor': '#10B981', 'tertiaryColor': '#F59E0B'}}}%%

    Workspace["工作区<br/>(Workspace)"] -->|"git add"| Index["暂存区<br/>(Index/Stage)"]
    Index -->|"git commit"| Repository["本地仓库<br/>(Local Repo)"]
    Repository -->|"git push"| Remote["远程仓库<br/>(Remote Repo)"]
    Remote -->|"git pull/fetch"| Repository
    Repository -->|"git checkout/restore"| Workspace
    
    classDef primary fill:#4F46E5,stroke:#3730A3,color:#fff
    class Workspace,Index,Repository,Remote primary

首先找到Xcode中的自带的配置文件

1

/Applications/Xcode.app/Contents/Frameworks/IDEKit.framework/Versions/A/Resources/IDETextKeyBindingSet.plist

这个文件里配置了一些可以设置快捷键的操作, 使用常用的编辑器打开它（需要root权限）。

执行命令安装vim 注意要加上--with-override-system-vi

1

brew install vim --with-override-system-vi

安装过程中如果出现 ruby.h找不到

执行下面的命令

1

cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/include/ruby-2.0.0/ruby

1

sudo ln -s ../universal-darwin15/ruby/config.h ./config.h

注意不要复制上面的, 对应自己的sdk版本,ruby版本,darwin版本
