我为自己编写了一个https://stackoverflow.com/a/50247503/3976739的简化版本(可能有一点效率)。我希望这能有所帮助。

void StrTokenizer(string& source, const char* delimiter, vector<string>& Tokens)
{   
   size_t new_index = 0;
   size_t old_index = 0;

   while (new_index != std::string::npos)   
   {
      new_index = source.find(delimiter, old_index);
      Tokens.emplace_back(source.substr(old_index, new_index-old_index));

      if (new_index != std::string::npos)
          old_index = ++new_index;
   }
}

您可以简单地使用正则表达式库并使用正则表达式解决该问题。

使用表达式(\w+)和\1中的变量(或$1，取决于正则表达式的库实现)。

MFC/ATL有一个非常好的标记器。从MSDN:

CAtlString str( "%First Second#Third" );
CAtlString resToken;
int curPos= 0;

resToken= str.Tokenize("% #",curPos);
while (resToken != "")
{
   printf("Resulting token: %s\n", resToken);
   resToken= str.Tokenize("% #",curPos);
};

Output

Resulting Token: First
Resulting Token: Second
Resulting Token: Third

下面是一种方法，允许您控制是否包含空标记(如strsep)或排除空标记(如strtok)。

#include <string.h> // for strchr and strlen

/*
 * want_empty_tokens==true  : include empty tokens, like strsep()
 * want_empty_tokens==false : exclude empty tokens, like strtok()
 */
std::vector<std::string> tokenize(const char* src,
                                  char delim,
                                  bool want_empty_tokens)
{
  std::vector<std::string> tokens;

  if (src and *src != '\0') // defensive
    while( true )  {
      const char* d = strchr(src, delim);
      size_t len = (d)? d-src : strlen(src);

      if (len or want_empty_tokens)
        tokens.push_back( std::string(src, len) ); // capture token

      if (d) src += len+1; else break;
    }

  return tokens;
}

使用regex_token_iterators的解决方案:

#include <iostream>
#include <regex>
#include <string>

using namespace std;

int main()
{
    string str("The quick brown fox");

    regex reg("\\s+");

    sregex_token_iterator iter(str.begin(), str.end(), reg, -1);
    sregex_token_iterator end;

    vector<string> vec(iter, end);

    for (auto a : vec)
    {
        cout << a << endl;
    }
}

简单的c++代码(标准c++ 98)，接受多个分隔符(在std::string中指定)，只使用向量、字符串和迭代器。

#include <iostream>
#include <vector>
#include <string>
#include <stdexcept> 

std::vector<std::string> 
split(const std::string& str, const std::string& delim){
    std::vector<std::string> result;
    if (str.empty())
        throw std::runtime_error("Can not tokenize an empty string!");
    std::string::const_iterator begin, str_it;
    begin = str_it = str.begin(); 
    do {
        while (delim.find(*str_it) == std::string::npos && str_it != str.end())
            str_it++; // find the position of the first delimiter in str
        std::string token = std::string(begin, str_it); // grab the token
        if (!token.empty()) // empty token only when str starts with a delimiter
            result.push_back(token); // push the token into a vector<string>
        while (delim.find(*str_it) != std::string::npos && str_it != str.end())
            str_it++; // ignore the additional consecutive delimiters
        begin = str_it; // process the remaining tokens
        } while (str_it != str.end());
    return result;
}

int main() {
    std::string test_string = ".this is.a.../.simple;;test;;;END";
    std::string delim = "; ./"; // string containing the delimiters
    std::vector<std::string> tokens = split(test_string, delim);           
    for (std::vector<std::string>::const_iterator it = tokens.begin(); 
        it != tokens.end(); it++)
            std::cout << *it << std::endl;
}
