Hi, I got this answer from one of the Chegg experts, " For database, u can create one in sqllite any any DBMS or u can store we have one here in excel file or .csv file */ " Can someone explain that to me?

I'm trying to create this database,

the following functions must be declared/defined in separate files: database.h and database.c.

int addRecord (struct record **, int, char [ ],char [ ]); void printAllRecords(struct record *); int findRecord (struct record *, int); int deleteRecord(struct record **, int);

Also the data structure of record (not sure about this)

Create record.h and define the following structure:

struct record { int accountno; char name[25]; char address[50]; struct record* next; };

Can someone help me and explain this to me I'm new at C and I'm not sure how to create this and implement it on the User_interface that I created. Thanks again for the help.
