student database

  Asked By: Tishad    Date: Dec 10    Category: C Programming    Views: 4352
  

Consider the following structure:
struct student
{
char name[20];
char semCode[10];
int enrollNo;
int assignSub;
int marks;
int attendence;
};
Please write functions to add, edit and delete record from a file database (Binary Read/Write). Write a
program to illustrate your work.
