<p>I've been having trouble deciphering some C++ code and haven't been able to find anything through search.  Can anyone help me out with the code below using the '&lt; ?' notation?</p>

<pre><code>int maximumLength(int countA, int countB, int maxA, int maxB) { 
    long long ca=countA,cb=countB,ma=maxA,mb=maxB; 
    if(ma==0) ca=0; 
    if(mb==0) cb=0; 
    long long res=ca+cb; 


    // any help on the below two lines is appreciated!
    res&lt;?=(cb+1)*ma+cb;
    res&lt;?=(ca+1)*mb+ca;

    return (int)(res); 
} 
</code></pre>
