Have to make truth tables

[ambanks04]

ok taking computer science class anybody know what to do i am not computer literate

CoSc 111.003 Spring 2008 Assignment 4

1) Each student shall design, develop, code, test and submit an
Original computer program which uses a function or functions to display the TRUTH TABLES for the Logical And, the Logical Or, and the Logical Not operators., as defined in Section 5.8, of the text, 5Th/6Th Edition.
2) The program shall:

a) Use a function to display the Logical And Truth Table, and
b) Use a function to display the Logical Or Truth Table, and
c) Use a function to display the Logical Not Truth Table, and
d) The main application program shall be prompt the user to choose which Truth Table to display, and
e) The main application program shall operate in a loop which allows the user to choose the Truth Tables , until the user signals to ‘Terminate’ the program, and
f) The main application program shall provide:
. A User friendly interface
. An interactive user interface, with
. Only keyboard and display as I/O devices

I guess you should try at least something; its not that tough,
infact its bit easy.
First of all just make a menu driven main function.
then make different functions; one for each logic operation; and u just have to display the table right?
So u dont even have to apply a logic for performing different operations.
Simply write a code for dislaying it.
Try it out.

Here's some info on truth tables
http://en.wikipedia.org/wiki/Truth_table

Here's the basics on how to write a very simple program:
http://www.engin.umd.umich.edu/CIS/course.des/cis400/cpp/hworld.html

The hello world program gets you started.
Things you will want to add to it are:
A method to prevent your console application from closing as soon as you execute it.
try searching google for "cin"

That should get you started...
then it would be a matter of:
using cout to give the "options"
and using cin to get the choices...

Try also doing a search for begginers C++ that will help.

thanks everybody i will be back if i have some more problems after trying it

i have the truth tables but what function would I use to tell the user to pick one truth table and only display that truth table i was thinking the if but not sure exactly what to do

[Ganon11]

You can have a function that will display a menu - something like:

Press 1 for option A,
Press 2 for option B,
Press 3 for option C,
Press Q to quit.

It will then get input from the user and, depending on which was entered, execute option A, B, or C, quit, or inform the user that an invalid choice was made.

My program isn't working I think I am using the void wrong. The compile log said this, and the rest is my program

I tried to do this as a function but I could not figure out why the void or was not working. It would not compile
