Undeclared identifier major problem
First of all id like to say Hi! im new to this forum and stumbled upon it via google really :) realllly need some help with this assignment im doing at University, i'm missing something pretty fundamental i think.
I have two classes, I first run the userdisplay and get values...these values are then calculated in the other class...but i cant get the classes to see the private variables such as Resistance. I have created 2 header files and 2 Cpp files
Code:
//Main Function - Responsible for Running program
//All C++ Projects need a main function
#include <iostream>
using namespace std;
#include "RLCSeriesCircuit.h"
#include "Simulation.h"
int main (void)
{
char Restart; //declare variable restart as type char
do
{
system("CLS"); //Clears the Screen (Stage 2 on Activity)
Simulation mySimulation; //object
mySimulation.Userdisplay(); //executes first function
cout << "\nDo you want to Restart the Program? (y/n): " ; //loop to restart whole program
cin >> Restart; //stores into char variable restart
}
while (Restart== 'y'); //Restarts if user enters in character y
cout << "\nEnd of program\n\n"; //outputs simple statement stating program has ended
system ("Pause"); //Pauses Program and displays "press any key to continue"
return 0;
}
Code:
//Header File for CLass Simulation
//Created by Daniel Jackson
#include <iostream>
using namespace std;
class Simulation
{
public:
void Userdisplay(void);
private:
double Resistance;
double Inductance;
double Capacitance;
double VS;
double MinFreq;
double MaxFreq;
double Freqsteps;
};

Examples of the errors im getting are above...seems no matter what i try i cannot call them variables....
