Add student entry
This function is used to add student records to the data file or .dat file that is used in the program.
There are structures made to take input from the user for the date and one for the student details.
The name of the function is new_entry(), the variables that are used is an integer variable named
as choice. FILE defines the two file pointers as *ptr and *hostel.
Source Code to Add student entry:
int new_entry()
{
int choice;
FILE *ptr,*hostel;
ptr=fopen("student_record.dat","a+");
printf("\t\t\t\******* ADD STUDENTS DATA *******\n");
