我使用这个simpleton是因为我们得到了字符串类“特殊”（即非标准）：

void splitString(const String &s, const String &delim, std::vector<String> &result) {
    const int l = delim.length();
    int f = 0;
    int i = s.indexOf(delim,f);
    while (i>=0) {
        String token( i-f > 0 ? s.substring(f,i-f) : "");
        result.push_back(token);
        f=i+l;
        i = s.indexOf(delim,f);
    }
    String token = s.substring(f);
    result.push_back(token);
}

#include <iostream>
#include <string>
#include <deque>

std::deque<std::string> split(
    const std::string& line, 
    std::string::value_type delimiter,
    bool skipEmpty = false
) {
    std::deque<std::string> parts{};

    if (!skipEmpty && !line.empty() && delimiter == line.at(0)) {
        parts.push_back({});
    }

    for (const std::string::value_type& c : line) {
        if (
            (
                c == delimiter 
                &&
                (skipEmpty ? (!parts.empty() && !parts.back().empty()) : true)
            )
            ||
            (c != delimiter && parts.empty())
        ) {
            parts.push_back({});
        }

        if (c != delimiter) {
            parts.back().push_back(c);
        }
    }

    if (skipEmpty && !parts.empty() && parts.back().empty()) {
        parts.pop_back();
    }

    return parts;
}

void test(const std::string& line) {
    std::cout << line << std::endl;

    std::cout << "skipEmpty=0 |";
    for (const std::string& part : split(line, ':')) {
        std::cout << part << '|';
    }
    std::cout << std::endl;

    std::cout << "skipEmpty=1 |";
    for (const std::string& part : split(line, ':', true)) {
        std::cout << part << '|';
    }
    std::cout << std::endl;

    std::cout << std::endl;
}

int main() {
    test("foo:bar:::baz");
    test("");
    test("foo");
    test(":");
    test("::");
    test(":foo");
    test("::foo");
    test(":foo:");
    test(":foo::");

    return 0;
}

输出：

foo:bar:::baz
skipEmpty=0 |foo|bar|||baz|
skipEmpty=1 |foo|bar|baz|


skipEmpty=0 |
skipEmpty=1 |

foo
skipEmpty=0 |foo|
skipEmpty=1 |foo|

:
skipEmpty=0 |||
skipEmpty=1 |

::
skipEmpty=0 ||||
skipEmpty=1 |

:foo
skipEmpty=0 ||foo|
skipEmpty=1 |foo|

::foo
skipEmpty=0 |||foo|
skipEmpty=1 |foo|

:foo:
skipEmpty=0 ||foo||
skipEmpty=1 |foo|

:foo::
skipEmpty=0 ||foo|||
skipEmpty=1 |foo|

谢谢@Jairo Abdiel Toribio Cisneros。它对我有效，但您的函数返回一些空元素。因此，对于没有空的返回，我编辑了以下内容：

std::vector<std::string> split(std::string str, const char* delim) {
    std::vector<std::string> v;
    std::string tmp;

    for(std::string::const_iterator i = str.begin(); i <= str.end(); ++i) {
        if(*i != *delim && i != str.end()) {
            tmp += *i;
        } else {
            if (tmp.length() > 0) {
                v.push_back(tmp);
            }
            tmp = "";
        }
    }

    return v;
}

使用：

std::string s = "one:two::three";
std::string delim = ":";
std::vector<std::string> vv = split(s, delim.c_str());

对于一个大得离谱而且可能是冗余的版本，可以尝试很多For循环。

string stringlist[10];
int count = 0;

for (int i = 0; i < sequence.length(); i++)
{
    if (sequence[i] == ' ')
    {
        stringlist[count] = sequence.substr(0, i);
        sequence.erase(0, i+1);
        i = 0;
        count++;
    }
    else if (i == sequence.length()-1)  // Last word
    {
        stringlist[count] = sequence.substr(0, i+1);
    }
}

它并不漂亮，但总的来说（除了标点符号和一系列其他错误）它是有效的！

LazyString拆分器：

#include <string>
#include <algorithm>
#include <unordered_set>

using namespace std;

class LazyStringSplitter
{
    string::const_iterator start, finish;
    unordered_set<char> chop;

public:

    // Empty Constructor
    explicit LazyStringSplitter()
    {}

    explicit LazyStringSplitter (const string cstr, const string delims)
        : start(cstr.begin())
        , finish(cstr.end())
        , chop(delims.begin(), delims.end())
    {}

    void operator () (const string cstr, const string delims)
    {
        chop.insert(delims.begin(), delims.end());
        start = cstr.begin();
        finish = cstr.end();
    }

    bool empty() const { return (start >= finish); }

    string next()
    {
        // return empty string
        // if ran out of characters
        if (empty())
            return string("");

        auto runner = find_if(start, finish, [&](char c) {
            return chop.count(c) == 1;
        });

        // construct next string
        string ret(start, runner);
        start = runner + 1;

        // Never return empty string
        // + tail recursion makes this method efficient
        return !ret.empty() ? ret : next();
    }
};

我将此方法称为LazyStringSplitter是因为一个原因——它不会一次性拆分字符串。本质上，它的行为类似于python生成器它公开了一个名为next的方法，该方法返回从原始字符串拆分的下一个字符串我使用了c++11STL中的无序集，因此查找分隔符的速度要快得多下面是它的工作原理

测试程序

#include <iostream>
using namespace std;

int main()
{
    LazyStringSplitter splitter;

    // split at the characters ' ', '!', '.', ','
    splitter("This, is a string. And here is another string! Let's test and see how well this does.", " !.,");

    while (!splitter.empty())
        cout << splitter.next() << endl;
    return 0;
}

输出，输出

This
is
a
string
And
here
is
another
string
Let's
test
and
see
how
well
this
does

改进这一点的下一个计划是实施开始和结束方法，以便可以执行以下操作：

vector<string> split_string(splitter.begin(), splitter.end());

我用这个分隔符分隔字符串。第一个将结果放入预先构建的向量中，第二个返回新向量。

#include <string>
#include <sstream>
#include <vector>
#include <iterator>

template <typename Out>
void split(const std::string &s, char delim, Out result) {
    std::istringstream iss(s);
    std::string item;
    while (std::getline(iss, item, delim)) {
        *result++ = item;
    }
}

std::vector<std::string> split(const std::string &s, char delim) {
    std::vector<std::string> elems;
    split(s, delim, std::back_inserter(elems));
    return elems;
}

请注意，此解决方案不会跳过空令牌，因此下面将找到4项，其中一项为空：

std::vector<std::string> x = split("one:two::three", ':');
