Converting string to float array

[an 0strich]

Hi am reading a file that looks like this:

230#Louis Christakes#1000#500
130#Paul Konerko#20000#50000 

It is for a bank account program in which a user can Add, Delete, Withdraw/Deposite Money from a Savings/Checking accounts and view account info from a bank. I read in all input with a string and now I can't get how to convert the Savings and Checking amounts to a float to then be able to withraw or deposite money. Then I would need to convert it back to string to save it again. Any help is appreaciated.

void bankBalance(Account [], int);

	Account *accountNum = new Account[20];
	int numOfCustomers = loadCustomers(accountNum);
	int choice = menu(numOfCustomers);

	while(choice > 7 || choice < 7)
	{
	
	if (choice == 1)
	{
