使用C ++ 11拆分字符串 [英] Split a string using C++11

问题描述

使用c ++ 11拆分字符串最简单的方法是什么？

What would be easiest method to split a string using c++11?

我已经看过这个 post ，但我认为应该有一个较为冗长的方式使用新的标准。

I've seen the method used by this post, but I feel that there ought to be a less verbose way of doing it using the new standard.

编辑：我想要一个向量< string> 作为结果，单字符。

I would like to have a vector<string> as a result and be able to delimitate on a single character.

推荐答案

std :: regex_token_iterator 基于正则表达式执行通用标记化。在单个字符上进行简单拆分可能是也可能不会过分，但它起作用并不太详细：

std::regex_token_iterator performs generic tokenization based on a regex. It may or may not be overkill for doing simple splitting on a single character, but it works and is not too verbose:

std::vector<std::string> split(const string& input, const string& regex) {
    // passing -1 as the submatch index parameter performs splitting
    std::regex re(regex);
    std::sregex_token_iterator
        first{input.begin(), input.end(), re, -1},
        last;
    return {first, last};
}
