Need help with my addressbook
Hi. I´m taking Borland C++ classes in school, and I´m making a project there. I´m going to make an adressbook, but I´m having some trubbel. Hope that someone could help me.
I want to be able to do these things:
*Enter persons and write them to a text file
*show the persons in the text file
*search for persons
I´ve managed to make a structure of the persons, each person have it´s attribute (name, address, age, id?) and I want to send these to the text file. But when I do this they are in Binary, how could I fix this?
I can´t find a good code for reading the persons, because I do not know how to give them a correct ID. So I need help with giving them an ID, and reading from the file.
Hope you understand and could help me with some of my problems.
