How to display the beginning balance read from the data file?
Okay so everytime i run the code and creates an infinite loop, but within that infinite loop the balance is displaying this huge number:
Balance = $-92559631349317830736831783200707727132248687965119994463780864.00
when i need it to display
Balance = 2000
