How to push into values into a stack from a text file

Question

I am trying to teach myself C++ with some programming assignments. Trying to learn using stacks but I am unsure how to push values from a txt file into a stack.

Let' say I have the following text file:

16 24 25 3 20 18 7 17 4 15 13 22 2 12 10 5 8 1 11 21 19 6 23 9 14

How would I use ifstream,and argv from the command line to push the values into a stack?

Did research and using this as help, but it may not be relevant:

How to push data of different data types into a vector by reading from a file?

The SO post you referenced seems to have almost everything you need. Replace the use of `std::vector` by `std::stack`. — R Sahu, Jun 30 '14 at 00:48
I wouldn't recommend as the linked posts accepted answer does. You might get well of with a simple [`std::back_inserter`](http://en.cppreference.com/w/cpp/iterator/back_inserter) and `std::istream` — πάντα ῥεῖ, Jun 30 '14 at 00:50

Here is something to get you started.

stack<int> data;
{
    ifstream file("file.txt");
    int i;
    while (file >> i)
    {
        data.push_back(i);
    }
}

There is no `push_back` on a stack. Its `push` – quantdev Jun 30 '14 at 03:19
