Explanation / Answer

/* prime2.C only worked for primes less than 10. An undetected overflow caused the program to give bogus answers. We must fix that by computing a^b % n without actually calculating a^b. The idea is to use the following property: (a * b) % n = ((a % n) * (b % n)) % n */ #include #include #include int fermatTest (int n) { int a, result, i; a = rand() % n; cout
