Bit manipulation program with binary operations

Posted on 16th Feb 2014 07:03 pm by admin

My homework is to create a program to scan in and add binary numbers and print them like so

Enter a binary number: 1

sum = 1 decimal 1 hex and 00000001 binary

Enter a binary number: 10

sum = 3 decimal 3 hex and 00000011 binary

etc.

I know that bit manipulation and input and output of strings is necessary to create this program, but I'm not experienced with either. The code I have compiles, but I am unable to make it do anything useful, and most of it is wrong. My do loop is probably wrong and I don't understand how to properly use bit manipulation. I'm rather clueless, can anyone give me some ideas on what to do next?
