void splitString(string str, char delim, string array[], const int arraySize)
{
    int delimPosition, subStrSize, subStrStart = 0;

    for (int index = 0; delimPosition != -1; index++)
    {
        delimPosition = str.find(delim, subStrStart);
        subStrSize = delimPosition - subStrStart;
        array[index] = str.substr(subStrStart, subStrSize);
        subStrStart =+ (delimPosition + 1);
    }
}

下面的代码使用strtok（）将字符串拆分为标记，并将标记存储在向量中。

#include <iostream>
#include <algorithm>
#include <vector>
#include <string>

using namespace std;


char one_line_string[] = "hello hi how are you nice weather we are having ok then bye";
char seps[]   = " ,\t\n";
char *token;



int main()
{
   vector<string> vec_String_Lines;
   token = strtok( one_line_string, seps );

   cout << "Extracting and storing data in a vector..\n\n\n";

   while( token != NULL )
   {
      vec_String_Lines.push_back(token);
      token = strtok( NULL, seps );
   }
     cout << "Displaying end result in vector line storage..\n\n";

    for ( int i = 0; i < vec_String_Lines.size(); ++i)
    cout << vec_String_Lines[i] << "\n";
    cout << "\n\n\n";


return 0;
}

作为一个业余爱好者，这是我想到的第一个解决方案。我有点好奇，为什么我还没有在这里看到类似的解决方案，是不是我的做法有根本问题？

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

std::vector<std::string> split(const std::string &s, const std::string &delims)
{
    std::vector<std::string> result;
    std::string::size_type pos = 0;
    while (std::string::npos != (pos = s.find_first_not_of(delims, pos))) {
        auto pos2 = s.find_first_of(delims, pos);
        result.emplace_back(s.substr(pos, std::string::npos == pos2 ? pos2 : pos2 - pos));
        pos = pos2;
    }
    return result;
}

int main()
{
    std::string text{"And then I said: \"I don't get it, why would you even do that!?\""};
    std::string delims{" :;\".,?!"};
    auto words = split(text, delims);
    std::cout << "\nSentence:\n  " << text << "\n\nWords:";
    for (const auto &w : words) {
        std::cout << "\n  " << w;
    }
    return 0;
}

这是我的版本获取了Kev的来源：

#include <string>
#include <vector>
void split(vector<string> &result, string str, char delim ) {
  string tmp;
  string::iterator i;
  result.clear();

  for(i = str.begin(); i <= str.end(); ++i) {
    if((const char)*i != delim  && i != str.end()) {
      tmp += *i;
    } else {
      result.push_back(tmp);
      tmp = "";
    }
  }
}

之后，调用函数并执行以下操作：

vector<string> hosts;
split(hosts, "192.168.1.2,192.168.1.3", ',');
for( size_t i = 0; i < hosts.size(); i++){
  cout <<  "Connecting host : " << hosts.at(i) << "..." << endl;
}

这是我的版本

#include <vector>

inline std::vector<std::string> Split(const std::string &str, const std::string &delim = " ")
{
    std::vector<std::string> tokens;
    if (str.size() > 0)
    {
        if (delim.size() > 0)
        {
            std::string::size_type currPos = 0, prevPos = 0;
            while ((currPos = str.find(delim, prevPos)) != std::string::npos)
            {
                std::string item = str.substr(prevPos, currPos - prevPos);
                if (item.size() > 0)
                {
                    tokens.push_back(item);
                }
                prevPos = currPos + 1;
            }
            tokens.push_back(str.substr(prevPos));
        }
        else
        {
            tokens.push_back(str);
        }
    }
    return tokens;
}

它适用于多字符分隔符。它防止空令牌进入结果。它使用单个标头。当您不提供分隔符时，它将字符串作为一个标记返回。如果字符串为空，它还会返回一个空结果。不幸的是，它的效率很低，因为存在巨大的std:：vector副本，除非您使用C++11进行编译，否则应该使用移动示意图。在C++11中，这段代码应该很快。

如果您喜欢使用boost，但希望使用整个字符串作为分隔符（而不是之前提出的大多数解决方案中的单个字符），可以使用boost_split_iterator。

示例代码包括方便的模板：

#include <iostream>
#include <vector>
#include <boost/algorithm/string.hpp>

template<typename _OutputIterator>
inline void split(
    const std::string& str, 
    const std::string& delim, 
    _OutputIterator result)
{
    using namespace boost::algorithm;
    typedef split_iterator<std::string::const_iterator> It;

    for(It iter=make_split_iterator(str, first_finder(delim, is_equal()));
            iter!=It();
            ++iter)
    {
        *(result++) = boost::copy_range<std::string>(*iter);
    }
}

int main(int argc, char* argv[])
{
    using namespace std;

    vector<string> splitted;
    split("HelloFOOworldFOO!", "FOO", back_inserter(splitted));

    // or directly to console, for example
    split("HelloFOOworldFOO!", "FOO", ostream_iterator<string>(cout, "\n"));
    return 0;
}
