I have to make a project of supermarket billing system.
I have made a file containing the [u]details of Some of the privelaged clients.[/u] It contains [u]their sr no.,name, ph no and membership[/u]. Now I need to access this file [size=4]everytime I make a new bill[/size] and the [size=4]customer name should be matched, in case it is found the membership should be returned.[/size] How do I do it?
