For this problem, assume 4 bits precision. Multiply binary two binary numbers, 1.100 two x 2 -4 and 1011 two x 2 -6 by showing the following steps:

Step1: Adding the exponent without bias.

Step2: Multiply the significands. (you can assume that you can carry all digits)

Step3: Normalize the product and check for an overflow or an underflow.

Step4: Truncate the product (to the original precision).

In a file-oriented information system, a work file stores relatively permanent data about an entity is created and saved for backup and recovery purposes stores records that contain day-to-day business and operational data is a temporary file created by an information system for a single task

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).
