CS301 Data Structure VU Assignment No. 2 Fall 2012

In digital computers, bit patterns are used to represent many types of data. Computers perform various operations on bit patterns. With a good representation scheme, bit patterns represent data and bit pattern manipulations represent operations on data. An important example of this is the Binary Addition Algorithm, where two bit patterns representing two integers, which are manipulated to create a third pattern which represents the sum of the integers.

Most processor chips implement the Binary Addition Algorithm in its silicon as part of their arithmetic logic unit.

Write a program in C++ which asks user to enter two binary numbers. Store these two numbers in two different stack variables (objects) bit by bit and calculate its sum and store it in another stack variable and display its sum.

Solution Guidelines:

1. Create a class named Bin_add (means stack class) that should contain following inline functions:

  • Constructor( ): To initialize “Bin_add” class data members.
  • Isempty( ):        To check whether a stack is empty or not.
  • Push( )              To push binary number bit by bit onto the stack
  • Pop( )               To pop bit (either 0 or 1) from the top of the stack
  • Add( )              To add two binary numbers bit by bit and display the sum.

 

2. In main function:

(a). Create three objects b1, b2, b_sum of type Bin_add class, two for input and one for storing the sum.

(b). Read two binary numbers from user bit by bit and push (insert) them in b1 and b2.

(c). Call the Add() function with b_sum object to add and display the sum of both binary numbers.
