std::experimental::erase_if (std::basic_string)
来自cppreference.com
< cpp | experimental
| 定义于头文件 <experimental/string>
|
||
| template <..., class Pred> void erase_if(std::basic_string<...>& c, Pred pred); |
(库基础 TS v2) | |
从容器擦除所有满足谓词 pred 的元素。等价于 c.erase(std::remove_if(c.begin(), c.end(), pred), c.end());
参数
| c | - | 要从中擦除的容器 |
| pred | - | 确定该擦除哪些元素的谓词 |
复杂度
线性。
示例
运行此代码
#include <experimental/string> #include <iostream> int main() { std::string data { "1337!p_C00L_<a-_HACKER_!@s_{!s#@_w^o%r*d#42" }; std::cout << "Original: \n\"" << data << "\"\n"; auto crack = [](auto O) { return O < 0141 or 0172 < O; }; std::experimental::erase_if(data, crack); std::cout << "After erase_if: \n\"" << data << "\"\n"; }
输出：
Original:
"1337!p_C00L_<a-_HACKER_!@s_{!s#@_w^o%r*d#42"
