Miller Rabin implementation with gmp library

First of all sorry for my english. I want to implement the Miller–Rabin primality test algorithm. I have to create two random numbers with 10 and 70 bits, respectively, and to check if that numbers are primes. I don't know a lot of stuff about programming so if someone could  help me i would very pleased.
