1 byte unsigned integer c++
<p>I have programmed a class called HugeInteger which can do arithmetic (add, sub, multiply) with numbers of "infinitely" size. It treats each bit of the digit in the number as a stand-alone digit (e.g. 1234 = 1, 2, 3 and 4). I store these numbers in a vector <code>(vector&lt;short&gt;)</code>. Now, because each digit only can take the values from 0 to 9, i don't really need to store them as a 2 byte digit. Is there a way (without using char) to store the digits as a 1 byte unsigned integer? Thanks!</p>

<p>Update:</p>

<pre><code>vector&lt;unsigned char&gt; v;
v.push_back(1);
v.push_back(2);

for (size_t i = 0; i &lt; v.size(); i++)
    cout &lt;&lt; v[i];
</code></pre>

<p>This produces an unwanted output. Which datatype should I use to iterate through the vector?</p>
