字符串操作

1.判断句子中是否同时含有多个字符串：

bool findstr_and(string str_org,initializer_list lst)
{
    
    for (auto i = lst.begin(); i != lst.end();i++)
    {
        if (str_org.find(*i) == str_org.npos)
        {
            return false;
        }
    }
    return true;
}

bool findstr_or(string str_org, initializer_list lst)
{

    for (auto i = lst.begin(); i != lst.end(); i++)
    {
        if (str_org.find(*i) != str_org.npos)
        {
            return true;
        }
    }
    return false;
}
