ISA vs. Microarchitecture [28 points] Classify the following attributes of a machine as either a property of its microarchitecture or ISA: (i) The programmer can index a memory location using the register rax. (ii) The register file has two read ports and two write ports. (iii) The processor is connected to 8GB RAM. (iv) There is an instruction that performs a matrix operation. (v) The instructions have a variable length. (vi) There are three levels of cache.

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
