是否有一种内置的方法来拆分C++中的字符串？

好吗？字符串我的意思是std :: string

这是我使用的perl风格的分割功能:

void split(const string& str, const string& delimiters , vector& tokens)
{
    // Skip delimiters at beginning.
    string::size_type lastPos = str.find_first_not_of(delimiters, 0);
    // Find first "non-delimiter".
    string::size_type pos     = str.find_first_of(delimiters, lastPos);

    while (string::npos != pos || string::npos != lastPos)
    {
        // Found a token, add it to the vector.
        tokens.push_back(str.substr(lastPos, pos - lastPos));
        // Skip delimiters.  Note the "not_of"
        lastPos = str.find_first_not_of(delimiters, pos);
        // Find next "non-delimiter"
        pos = str.find_first_of(delimiters, lastPos);
    }
}

std::istringstream oss(std::string("This is a test string"));
std::string word;
while(oss >> word) {
    std::cout << "[" << word << "] ";
}

std::string str = "hello world";

std::string::const_iterator pos = std::find(string.begin(), string.end(), ' '); // Split at ' '.

std::string left(str.begin(), pos);
std::string right(pos + 1, str.end());

// Echoes "hello|world".
std::cout << left << "|" << right << std::endl;
