| ## 基于范围的循环
 | |
| 
 | |
| 基于范围的`for`循环允许在一系列元素(如容器中的元素)上轻松循环。
 | |
| 
 | |
| 使用传统的`for`循环:
 | |
| 
 | |
| ```cpp
 | |
| std::vector<std::string> stringList {"one", "two", "three"}; 
 | |
|  
 | |
|  for (size_t il; il < stringList.size(); il++ 
 | |
|  { 
 | |
|   std::cout << stringList.at(il) << std::endl; 
 | |
|  } 
 | |
| ```
 | |
| 
 | |
| 使用基于范围的`for`循环:
 | |
| 
 | |
| ```cpp
 | |
| std::vector<std::string> stringList {"one", "two", "three"}; 
 | |
|  
 | |
|  for (auto& singleString : stringList) 
 | |
|  { 
 | |
|   std:cout << singleString << std::endl; 
 | |
|  } 
 | |
| 
 | |
| ``` |
