#define ENTER 13

#define TAB 9

#define BKSP 8

char pwd[100];

int main(){

int i= 0;

char ch;

printf("enter your password.Hit enter to conform.\n");

printf("password:");

while(1){

ch = getch(); //GET KEY

if(ch == ENTER || ch ==TAB)

    {

        pwd[i] = '\0';

break;

}else if(ch== BKSP){

if(i>0){

i--;

printf("\b \b");

}

}else{

 pwd[i++]= ch;

 printf("* \b");

 }

} //while ends here

printf("\n\nPassword:%s \n Length:%d");

return 0;

} //main() ends here
