这是我使用C++11和STL的解决方案。它应该是合理有效的：

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

std::vector<std::string> split(const std::string& s)
{
    std::vector<std::string> v;

    const auto end = s.end();
    auto to = s.begin();
    decltype(to) from;

    while((from = std::find_if(to, end,
        [](char c){ return !std::isspace(c); })) != end)
    {
        to = std::find_if(from, end, [](char c){ return std::isspace(c); });
        v.emplace_back(from, to);
    }

    return v;
}

int main()
{
    std::string s = "this is the string  to  split";

    auto v = split(s);

    for(auto&& s: v)
        std::cout << s << '\n';
}

输出：

this
is
the
string
to
split

使用Boost的可能解决方案可能是：

#include <boost/algorithm/string.hpp>
std::vector<std::string> strs;
boost::split(strs, "string to split", boost::is_any_of("\t "));

这种方法可能比字符串流方法更快。由于这是一个通用模板函数，因此可以使用各种分隔符拆分其他类型的字符串（wchar等或UTF-8）。

有关详细信息，请参阅文档。

这个答案将字符串放入字符串向量中。它使用boost库。

#include <boost/algorithm/string.hpp>
std::vector<std::string> strs;
boost::split(strs, "string to split", boost::is_any_of("\t "));

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;
}

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);
    }
}

对于那个些需要使用字符串分隔符拆分字符串的人，也许可以尝试我的以下解决方案。

std::vector<size_t> str_pos(const std::string &search, const std::string &target)
{
    std::vector<size_t> founds;

    if(!search.empty())
    {
        size_t start_pos = 0;

        while (true)
        {
            size_t found_pos = target.find(search, start_pos);

            if(found_pos != std::string::npos)
            {
                size_t found = found_pos;

                founds.push_back(found);

                start_pos = (found_pos + 1);
            }
            else
            {
                break;
            }
        }
    }

    return founds;
}

std::string str_sub_index(size_t begin_index, size_t end_index, const std::string &target)
{
    std::string sub;

    size_t size = target.length();

    const char* copy = target.c_str();

    for(size_t i = begin_index; i <= end_index; i++)
    {
        if(i >= size)
        {
            break;
        }
        else
        {
            char c = copy[i];

            sub += c;
        }
    }

    return sub;
}

std::vector<std::string> str_split(const std::string &delimiter, const std::string &target)
{
    std::vector<std::string> splits;

    if(!delimiter.empty())
    {
        std::vector<size_t> founds = str_pos(delimiter, target);

        size_t founds_size = founds.size();

        if(founds_size > 0)
        {
            size_t search_len = delimiter.length();

            size_t begin_index = 0;

            for(int i = 0; i <= founds_size; i++)
            {
                std::string sub;

                if(i != founds_size)
                {
                    size_t pos  = founds.at(i);

                    sub = str_sub_index(begin_index, pos - 1, target);

                    begin_index = (pos + search_len);
                }
                else
                {
                    sub = str_sub_index(begin_index, (target.length() - 1), target);
                }

                splits.push_back(sub);
            }
        }
    }

    return splits;
}

这些片段由3个函数组成。坏消息是使用str_split函数，您将需要另外两个函数。是的，这是一大块代码。但好消息是，这两个附加功能可以独立工作，有时也很有用

测试main（）块中的函数如下：

int main()
{
    std::string s = "Hello, world! We need to make the world a better place. Because your world is also my world, and our children's world.";

    std::vector<std::string> split = str_split("world", s);

    for(int i = 0; i < split.size(); i++)
    {
        std::cout << split[i] << std::endl;
    }
}

它将产生：

Hello, 
! We need to make the 
 a better place. Because your 
 is also my 
, and our children's 
.

我认为这不是最有效的代码，但至少它可以工作。希望有帮助。
