Turbo C | Help Needed

[prateek]

Hello,

Program more simplified by me

there is only one last problem
why is the @ sign OR ANY OTHER GRABAGE VALUE comming at the end of the password ??

#include<stdio.h>
#include<conio.h>
#include<string.h>
main()
{
    clrscr();
    char pass[32], ch;
    printf("Enter Password : ");
    int j=0;
    while(1)
    {
    ch=getch();
    if(ch=='q' || ch=='Q')
    break;
    pass[j]=ch;
    putchar('*');
    j=j+1;
    }
    j=j+1;
    pass[j]='\0';
    printf("\n\n Password is : %s",pass);
    getch();
}
