//system("pause");

}

The not recommended way but easiest way would be to declare two global variables initialised to zero, checkingBalance and savingsBalance and use them in all functions that need them.

The recommended way is to declare them in main() and pass them as references to all the functions but you will have to study up on function parameters and arguments.
