How do i fix NTL PowerMod issue
<p>ZZ PowerMod(const ZZ&amp; a, const ZZ&amp; e, const ZZ&amp; n)</p>

<p>I did the following</p>

<p>ZZ a,b,c;</p>

<p>a=13;
b=1;
c=11;</p>

<p>ZZ result;</p>

<p>result = PowerMod(a,b,c);</p>

<p>I tried to compile and run, it say PowerMod error , bad args. </p>

<p>It only accept long,long,long and return long type.. but issue is I did use PowerMod with ZZ on my previous other cpp file and its fine.</p>

<pre><code>void PowerMod(ZZ&amp; x, const ZZ&amp; a, const ZZ&amp; e, const ZZ&amp; n);
ZZ PowerMod(const ZZ&amp; a, const ZZ&amp; e, const ZZ&amp; n);
</code></pre>
