my program logic : user open the program daily, enter the amount spent, program will create / read and record the number, user closed the program, continue next day..
The challenge :
I set the total saving of user to a fixed amount. However if the program once closed, the program can't work, it will just deduct from the fixed amount, so i plan to read the latest saving (or you guys have better way?)
Let say I have this in a file
Date Amount spend Saving left
11/23/11 -20.00USD 980.00USD
How to read just only the "RM 980.00"? read the last few char of the file? or use seek? I'm a newbie..
