Question

Dear experts Im really having a hard time understanding this program if you could please help me figure out the program it would be of great help to me. I have not done C++ In years and need to know step by step how to do this program becuase it a multifile and I can not get it run correctly.
1. Add three classes to the project: a Filter class, a Capacitor class, and a Resistor class..
2. The Capacitor class should be modeled after the Resistor class for class members and operation.

STEP 2: Filter-Class Definition


The Filter class should have, at a minimum, the following capabilities.

a resistor-object data member
a capacitor-object data member
a cutoff frequency (in Hertz) of the RC filter
maximum and minimum cutoff frequencies, based on the maximum and minimum in-tolerance values of the capacitor and the resistor object
a filter type, either low pass or high pass
allow the user to enter new values for the filter, including
6.1. resistor tolerance and nominal resistance;
6.2. capacitor tolerance and nominal capacitance; and
6.3. filter type
provides the ability to write all capacitor, resistor, and filter data members to a formatted text file and allows the user to name the file
provides the ability to read all capacitor, resistor, and filter data members from a formatted text file and allows the user to enter the file name and correctly handles a file-not-found error
STEP 3: Test-Program Operation


All data-input and data-display operations (cin and cout) should be done in the function main() test program.
The test program should instantiate at least one object of the class Filter.
The user should enter values for all the data members of the Filter, Resistor, and Capacitor classes.
The Filter class should then calculate and display the correct maximum and minimum cutoff frequencies.
The test program should then display all Filter, Resistor, and Capacitor data members.

Explanation / Answer

#pragma once; #include #include #include #include #include #include using namespace std; const double PI=3.1415927; class CResistor { protected: double res_kohms; public: void setResistance(); double getResistance(); }; class CCapacitor { protected: double cap_uF; public: void setCapacitance(); double getCapacitance(); }; class RCFilter { protected: CResistor resistor; CCapacitor capacitor; char filterType; double frequency; public: void setResistance(); void setCapacitance(); void setFilterType(); double getFrequency(); void showFrequency(); void showfilterDesign(); }; COORD getXY(); void gotoXY(int nX, int nY); // RCFilter.cpp #include "RCFilter.h" void CResistor::setResistance() { } double CResistor::getResistance() { return 1.0; } void CCapacitor::setCapacitance() { } double CCapacitor::getCapacitance() { return 1.0; } void RCFilter::setResistance() { } void RCFilter::setCapacitance() { } void RCFilter::setFilterType() { } double RCFilter::getFrequency() { return 1.0; } void RCFilter::showFrequency() { } void RCFilter::showfilterDesign() { if (filterType=='L') { } else { } cout dwCursorPosition.Y; delete pBuffer; return Coordinates; } // RCFilter-Main.cpp // #include "RCFilter.h" void main() { RCFilter rcf; char ch; do { system("CLS"); cout
