I am using files to store some numbers in my program. I am storing a string on one line and then a number on another and it repeats (so i've got a client/number sort of system). I can use getline to get that information out of the file but I can't use the number. I need to be able to perform addition and subtraction on the numer... how can I do this?
Also, is there a way to edit a specific part of a file (ie. alter the number and leave the rest as is?).
I am using Borland C++ Builder 5:
Thanks for any help you can provide -
