I had made a video library program in C++, but was facing a problem.
After entering 12 movies, i cannot enter any more movies.
Something gibberish comes instead.
Can somebody please tell whats wrong??
This is the code : :
#include<fstream.h>
#include<conio.h>
#include<stdio.h>
#include<process.h>
#include<string.h>
#include<dos.h>
/*
USE OF HEADER FILES :
FSTREAM.H = FOR DATABASE MANAGEMENT(STREAMS ETC...), IOSTREAM.H
CONIO.H = FOR TEXTCOLOR, CLRSCR(), GETCH() ETC...
STDIO.H = RENAME, REMOVE, GETS(), PUTS() ETC...
PROCESS.H = FOR EXIT()
STRING.H = FOR STRING RELATED FUNCTIONS
DOS.H = FOR _DOS_GETDATE FUNCTION
*/
void pass(); //TO INPUT A PASSWORD TO ACCESS THE PROGRAM
struct date1
{
int dd, mm, yyyy;
};
struct dosdate_t d; //TO GET CURRENT DATE
