Hey dudes,
I got this question that i am working on currently. But, having problems.. I just need help on the errors. and how to fix them.
Here is the question: --------------------------
Design an object oriented program which computes and returns the output (0 or 1) for the AND, OR, NAND and NOR gate respectively.
Create a Gate class that contains the following members:
-data members to store two inputs and an output of a gate
-four inline member functions that compute and return the output for the AND, OR, NAND and NOR gate respectively
-a non-inline function that displays menu options (types of gates available) when choosing a type of the gate
-a non-inline function that gets two inputs of the gate from the user
-a constructor function that initializes two inputs of the gate
SAMPLE OUTPUT LOOKS LIKE THIS:
Types of gates available:
1. AND
2. OR
3. NAND
4. NOR
Choose the type of gate for gate 1 => 1
Enter two inputs for gate 1 => 0 1
Choose the type of gate for gate 2 => 3
Enter two inputs for gate 2 => 1 0
Choose the type of gate for gate 3 => 2
Outputs =>
y1 = 0
y2 = 1
y3 = 1
--------------------------

#include <iostream>
#include <stdlib.h>
#include<conio.h>
using namespace std;

I got whole bunch of INITIAL ERROS on the op_and function, and the rest..that they haven't been declared etc..

SOLUTION
membership
This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
also, to be able to create an instence of Gate class without passing any parameters,
U could write the above constructor as
Gate::Gate (int in1 = 0, int in2 = 0) {
x1 = in1 ;
x2 = in2 ;
}
so that by default the x and y inputs get initialized to 0 if the user does not pass aything.

ASKER
thanks to everybody who helped me out. I finished my assignment successfully!
U have declared it as a member, but while defining, u are defininfg it as a standalone function
So i changed this line in your program
int schoice (int choice, int in1, int in2){
to
int Gate::schoice (int choice, int in1, int in2){
2.
A closing brace is missing for the switch statement in schoice
3.
In main, u have declared a Gate variable passing no parameters to constructir
Since u have declared one constructor taking parameter, u should define a no argument [or construcor with all arguments having default values] constructor to define a variable without requiring to pass parameters.
