Adigital computer has a memory unit with 48 bits per word. the instruction set consists of 240 different operations. all instructions have an operation code part (opcode) and an address part (allowing for only one address). each instruction is stored in one word of memory.
a. how many bits are needed for the opcode?
b. how many bits are needed to specify the register? how many bits are left for the address part of the instruction?
c. what is the largest unsigned binary number that can be accommodated in one word of memory?

Problem 3: (hand) write the member function implementations for the class hand, which simulates a hand of 2 cards, into the file hand.cpp. the relative strength of 2 hands are determined by the following rules: • a pair (two cards of the same number) is the strongest hand. • two cards of the same suit is the next strongest hand. • two cards of different numbers and suits is the weakest hand. • within the same kind of hands, the stronger hand is determined by the larger number. • if two hands are of the same kind and the larger numbers are the same, the stronger hand is given by the hand whose smaller number is larger. • if all above fails, the two hands are of equal strength. i.e., all suits are of equal strength. • 2 is the weakest number. an ace is stronger than a king. you are using a single deck of cards. so a hand of a♥a♥ is impossible. here are some examples:
