Question

I just has a vector like that

vector<User*> users;

I know it is not a good programming style…

now I have a function

vector<User> getAllUser(void)
{
}

What I had tried is

vector<User> getAllUser(void)
{
    vector<User> result;
    for (vector<User*>::iterator it = users.begin(); it != users.end(); it++)
    {
        result.push_back(**it);
    }
    return result;
}

But it didn’t work.

Could someone to help me? Thankyou very much. I am just a beginner to STL

You code should work, but you made a typo:

result.push_bach(**it);

push_bach is not a declared function for std::vector, so I’m assuming that’s where the error lies. I would recommend you get a decent compiler, which should point this error out to you right away, without having to go through stackoverflow.

To fix, use the proper method name, push_back instead:

result.push_back(**it);
