You need to show what you have tried first.

Read this http://www.egr.msu.edu/classes/ece410/mason/files/Ch12.pdf. Then show your code if you have problems.

What exactly is the input, what the expected output?
Cheers

Solution 1

With so little information you give, I can only guess what you need.
I have to make some assumptions:
- input: bool a_in, b_in, c_in
- output: bool a_out, b_out, c_out

Now you can easily implement the functions from the truth-table of the full adder:
- a_out = f_a(a_in, b_in, c_in)
- b_out = f_b(a_in, b_in, c_in)
- c_out = f_c(a_in, b_in, c_in)

The implementation of the functions might be in form of
- Boolean expressions
- lookup table

Implementing in C++ is left to you as exercise.

Cheers

5ed.

Andi,

Congratulations with April 1st! :-)

I would like to use the occasion to invite your (and everyone else, of course) to see my new 1 of April publication and have some fun:
Some Programming Approaches to "Neuro-Linguistic Programming".
Participation in this game in Comments and Discussions is especially encouraged.

I always appreciated your expert's answers and comments.

Thank you.

Hello Sergey,
I'm glad to come back to read and appreciate your great article in full detail (i.e. following the many links ;-)) in the near future when I'm less "overloaded" - in a different sense as detailed in your April 1 article :-).
Great reading!
Cheers
Andi

Thank you, Andi.
Yes, the links, especially many unexpected links are important.
Hope you will have fun with it.
