I wrote this program... Just gave a try!!
i got a problem with searching a string in file.. the "checkp" used in the login function, returns a value "1", whereas it must return a value "0" Hence my program fails...
what i felt is, the file i'm opening, "web_reg.txt", in that, extra spaces are coming...
Does anyone knows, to sort this out???? Please help me!!
please check it out in your PC's.
Thanks a lottt
The code is as following:
#include<conio.h>
#include<stdio.h>
#include<string.h>
struct web

if(getchar()=='\n')
clrscr();
printf("\n\n\n\t\t\t1. LOGIN\t\t2. REGISTER");
printf("\n\n\n\t\t\t\tENTER YOUR CHOICE: ");
scanf("%d",&n);
switch(n)
{
case 1: clrscr();
login();
case 2: clrscr();
reg();
}
}
void reg()
{

}
