This is an ATM style program, but currently it doesn't do exactly what I need it to do...
I need to get the current balance, and when money is transferred from either checking or savings, it should add it to checking and subtract it from savings. which is does, but not correctly...
Input example
-=[ Funds Transfer ]=-
-=[ Savings to Checking ]=-
Account Name: nomadic
Amount to transfer: $400
New Balance in Checking: $900 // original was 500
New Balance in Savings: $7.7068e+012 // this should now be 1100...
Here is my code, it's a lot of code, but there are no errors, so throwing it into an IDE and compiling should be fairly quick for whoever would like to help.
