## 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;
|
||
|
}
|
||
|
|
||
|
```
