**C ** Add five additional functions to this code

timer Asked: Apr 1st, 2016

Question description

Add five additional functions (services/options you have available when you use the ATM machine or bank with a cashier).

Submit two files: 

a cpp file for the source you wrote

a pdf file of the source you wrote; color in blue or red the five functions you added (this will help me in the grading process).

#include <iostream>
using namespace std;

double transaction;
double currentBalance (5000);

char pickTransaction(void);
void message (void);
void deposit(void);
void withdraw(void);

// This code only perform one transaction. Modify it to give the user opportunity to perform as many operations as she/he desires.
int main()
	cout << " Welcome to Your Bank! \n" << endl;
	char letter = pickTransaction();
	if ((letter == 'D') || (letter == 'd'))
	if ((letter == 'W') || (letter == 'w'))
	if ((letter == 'B') || (letter == 'b'))
	system ("pause");
	return 0;

char pickTransaction()
	char input;
	do {
		cout << "What transaction would you like to perform today? Enter D for Deposit, W for Withdraw, or B to see your Balance \n";	
		cin >> input;
	while ((input != 'B') && (input != 'b') && (input != 'W') && (input != 'w')&& (input != 'D')&& (input != 'd'));
	return input;

void message (void)
	cout << " your new balance is: $" << currentBalance << endl;

void deposit(void)
	cout << "How much do you want to deposit? \n";
	cin >> transaction;
	currentBalance = currentBalance + transaction;

void withdraw(void)
	cout << "How much do you want to withdraw? \n";
	cin >> transaction;
	if (currentBalance <=0)
	{cout << " Your balance is low; transaction cannot be performed. \n";}
	{currentBalance = currentBalance - transaction;}
