C++分割字符串

从这里拿来改进了点，亲测可用。

void stringSplit(const std::string& sourceStr, const std::string& delimiter, std::vector& result)
{
    size_t last = 0;
    size_t next = 0;
    std::string token;
    while ((next = sourceStr.find(delimiter, last)) != std::string::npos)
    {
        if (next > last)
        {
            token = sourceStr.substr(last, next-last);
            result.push_back(token);
        }
        
        last = next+delimiter.length();
    }

    if (last < sourceStr.length())
    {
        token = sourceStr.substr(last);
        result.push_back(token);
    }
}

测试如下，

int main(void)
{
    std::string s = "scott>=tiger>=mushroom";
    std::string delimiter = ">=";
    std::vector result;

    stringSplit(s, delimiter, result);

    for (auto it = result.cbegin(); it != result.cend(); ++it)
    {
        std::cout << *it << "n";
    }

    return 0;
}

结果如下，
