Automated Teller Question

[nitro2gomike]

I am writing what I hear is a very basic program. However, I am still learning how to decipher these hieroglyphics so you may be able to relate to my madness when you were just beginning. I actually got a good portion of it written through pointers in the book I am using but I'm having trouble coming up with code for each case. Any pointers or suggestions would be greatly appreciated.
Thank you

#include <iostream>
#include <iomainip>  // for 'fixed' and 'setprecision'

// function main begins program execution
int main ()
{
	double account1 = 100;
	double account2 = 50;

	// display initial balance of each account
	std::cout << "Account 1 balance: $500" << std::setprecision (2) << std::fixed << account1 <<
    std::endl;
	std::count << "Account 2 balance: $1000" << std::setprecision (2) << std::fixed <<account2 <<
	std::endl;

	// a variable to hold their choice
	int selection = 0;
	// a variable to track the number of transactions
	int transactions = 0;
	while (selection != 5)
	{
		// Display a menu to the user
		// You MUST use thee integer values (1-5) for the auto evaluator to work
		std::cout << "(1) to debit account 1" << std::endl;
		std::cout << "(2) to debit account 2" << std::endl;
		std::cout << "(3) to transfer from account 1 to 2" << std::endl;
		std::cout << "(4) to transfer from account 2 to 1" << std::endl;
		std::cout << "(5) to exit" << std::endl; // sentinel value

		// Ask the user for their choice
		std::cout << "What would you like to do? ";
std:cin >> selection;

		// Use a switch statement to detect their option switch (selection)
	{
		case 1;
		 // Write code to debit account1
		 // Aske the user for an amount
		 // debit the account if possible
		 // done
		break;
		case 2:
		 // Write code to transfer from account 1 to account 2
		 // Write code to transfer from account 1 to account 2
		 // Ask the user for an amount
		 // transfer the amount if possible
		 // done
		break;
