does this program contain class's

[ProgramMaster]

Alright I'm not quit sure what a class is but does the following programing contain any

Menubuilder.cpp

 #ifndef _MenuBuiler_CPP_
#define _MenuBuilder_CPP_
#include "Menubuilder.h"

  double balance =2439.45;
  double Amount;
  double Ebalance;
 

void checkBal()
{
	cout<<"current balance is:$"<<balance<<endl;
}
double withD()
{
  cout<<"How much would you like to withdraw?\n";
  cin>>Amount;
  Ebalance= balance - Amount;
  cout<<"current balance remaining:$ "<<Ebalance<<endl;

  return Ebalance;
}
double Depo()
{
	cout<<"how much would you like to deposit?\n";
	cin>>Amount;
	Ebalance= balance +Amount;
	cout<<"current balance remaining:$ "<<Ebalance<<endl;

	return Ebalance;
}
void AccountI()
{
	cout<<"Name: \t Samantha Jane\n";
	cout<<"Account number:\t 1234554321"<<endl;
}
void VeiwState()
{
	cout<<"01/01/11 - McDonald's - $6.27\n";
	cout<<"01/15/11 - Kwik Trip - $34.93\n";
	cout<<"02/28/11 - Targer - $124.21"<<endl;
}
void BankI()
{
	cout<<"Devry Bank, established 2011\n";
	cout<<"[phone]\n";
	cout<<"12345 1st St.\n";
	cout<<"somplace, NJ 12345";
}
int Exit()
{
	return 0;
}
#endif // !1 

TestMenu.cpp

#ifndef _TestMenu_CPP_
#define _TestMenu_CPP_
#include "Menubuilder.h"
 // !1
 
  int Choice;
using namespace std;

int main()
{
	while(Choice !=7 )
	{
		cout<<"\t\n";
	cout<<"Welcome to the DeVry Bank Automated Teller Machine\n";
	cout<<"1.Check balance\n";
	cout<<"2.Make withdrawal\n";
	cout<<"3.Make deposit\n";
	cout<<"4.View account information\n";
	cout<<"5.View statement\n";
	cout<<"6.View bank information\n";
	cout<<"7.Exit"<<endl;
cin>>Choice;
  switch(Choice)
  {
  case 1: checkBal();
	  break;
  case 2: withD();
	  break;
  case 3: Depo();
	  break;
  case 4: AccountI();
	  break;
  case 5: VeiwState();
	  break;
  case 6: BankI();
	  break;
  case 7: Exit();
	  break;
  }
	}
}
#endif

MenuBuiler.h

#ifndef MenuBilder_H_
#define MenuBuilder_H_

#include <iostream>
#include <iomanip>

using namespace std;


 
 extern double Amount;
 extern double Ebalance;
 extern int Choice;


void checkBal();
double withD();
double Depo();
void AccountI();
void VeiwState();
void BankI();
int Exit();

#endif 

And if not how could I possible implement a few into it .

a) you dont need include guards in a .c(pp) file
b) there arent any user made classes in that file. you can tell its a class or data structure by seeing the keywords class or struct

Alright now My main functions are not able to be defines I don't understand I thought I defined everything right

#include "Menubuilder.h"

  double balance =2439.45;
  double Amount;
  double Ebalance;
 class TestMenu {
 public:
void checkBal()
{
	cout<<"current balance is:$"<<balance<<endl;
}
double withD()
{
  cout<<"How much would you like to withdraw?\n";
  cin>>Amount;
  Ebalance= balance - Amount;
  cout<<"current balance remaining:$ "<<Ebalance<<endl;

  return Ebalance;
}
double Depo()
{
	cout<<"how much would you like to deposit?\n";
	cin>>Amount;
	Ebalance= balance +Amount;
	cout<<"current balance remaining:$ "<<Ebalance<<endl;

	return Ebalance;
}
void AccountI()
{
	cout<<"Name: \t Samantha Jane\n";
	cout<<"Account number:\t 1234554321"<<endl;
}
