Put your input statement in a loop, when they have given an input check it's value and if it is wrong print an error message and ask for another input.

Hi Check the code below, You will get some idea

void getpass(char passwd[])
{
int ch;
while(1)
{
printf("Enter your password : ");
u_int index=0;
while((ch=getch())!=13)
{
if(index < 8)
{
passwd[index]=ch;
}
index++;
putch('*');
}
if(index <2 || index > 8)//enter key
{
printf("\nPassword should be more than 1 and less than 9 charactes");
printf("\nPress any key to enter again...");
while(!_kbhit());
system("cls");
getch();
continue;
}
else
{
passwd[index]='\0';
break;
}
}
}
int main(int argc,char* argv[])
{
char passwd[9];
getpass(passwd);
printf("\npassword : %s\n",passwd);
return 0;
}

yep.. yr code looks complicated.. not really understand.. can u check this example? how the array length is not 6 as i declared?

#include <stdio.h>
#include <string.h>
main ()
{
char a[8];
int size;

clrscr();
printf("Input1 : ");
scanf("%s",&a);
length = strlen(a);
printf("\nlength this input is = %d",length);

if (length <=8)
{ ... proceed instruction here}
else
{ print error}

getch();
}

i try the strlen just now... the program ok, no problem but new prob appear.
i have prob with this short prog (eample), output doesn't capture any Y or N char.... why ? and how to correct it?

char answer;
do
{ //some instruction goes here

printf("Are u sure to checkout ?Y/N ");
scanf("%c",&answer);
}
while((answer != 'N') || (answer != 'n');
