I am trying to learn about how to use classes with private and public variables in c++. I've got a conversion program that I would like to use as a prop.

If I was to add a class to this program, what I think I know is...

(Just to say, this is still fresh and I don't have a full grasp of all the concepts yet)

I know that to start a class, you must first declare it like for example...

class Conversion
int inches;
int foot;

void conversion(int happen);

// 244228-classExample.cpp : Defines the entry point for the console application.

#include "stdafx.h"

#include <iostream>

using namespace std;

class Conversion
float inches; // number of inches
float foot; //number of feet
float centimeters; // number of centimeters

inches = 0;
foot = 0;
centimeters = 0;
void convert();
float getInches();
void setInches(float in);
float getFoot();
void setFoot(float ft);
float getCentimeters();
void showOutput();

float Conversion::getInches(){
return inches;

void Conversion::setInches(float in){
inches = ...
