c++ - How do i fix NTL PowerMod issue -

-

zz powermod(const zz& a, const zz& e, const zz& n)

i did following

zz a,b,c;

a=13; b=1; c=11;

zz result;

result = powermod(a,b,c);

i tried compile , run, powermod error , bad args.

it accept long,long,long , return long type.. issue did use powermod zz on previous other cpp file , fine.

void powermod(zz& x, const zz& a, const zz& e, const zz& n); zz powermod(const zz& a, const zz& e, const zz& n);

i know question bit old, i'll leave answer stumbling along looking answer find one.

according this: http://forums.codeguru.com/showthread.php?506099-ntl-problem

a must smaller n. don't know if problem, try: powermod(a % n, e, n)
