Bit manipulation program with binary operations
Posted on

My homework is to create a program to scan in and add binary numbers and print them like so
Enter a binary number: 1
Did you know?Explore Trending and Topic pages for more stories like this.
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?
