Searching for an appropriate data structure in C++ to push into vector
<p>I want the following to be pushed in a vector, which data structure is suitable for the same:
I want to push:</p>

<pre><code>(1, 10)
(2, 11)
(3, 12)
</code></pre>

<p>I know how to push into a vector an integer but i am not sure about the list that i have now. I am looking for a data structure which is memory efficient. I know i can use a vector as well as list in this case, but which one is memory efficient. If there is any other data structure which is memory efficient then please suggest.</p>
