    If you are required to do it that means that you should be able to do it yourself. I don't really know c or I would help you, but Try doing a few searches on google until someone who actually knows c answers your question. Hope you get your answer.

    damn h3r3tic, seems like you get more and more APs everyday

    i think that this question should have been in the code review section of AO...

    well i know how to do it in C++, i typed it up real fast...
    Code:
    #include <windows.h>
    #include <iostream>
    using std::cout;
    using std::cin;
    using std::endl;
    
    char password[11];
    
    int main (void)
    {
    	for (int x=0;x<11;x++)//take in your lame password
    	{
    		cout << "Please enter your 11 character password..." << endl;
    		cin >> password[x];
    		clrscr();//clears the screen
    	}
    	
    	cout << "Your password is:" << endl;
    	for (int x=0;x<11;x++)//now it will tell you your lame password
    	{
    		cout << password[x];
    	}
    }
    It is pretty simple actually, just take characters in, clear the screen, then at the end, print all the characters out...this was a really shitty way of doing it, but it worked...quick and dirty baby

    Code:
    #include<stdio.h>
    #include<string.h>
    void main(void)
    {
    	char ch,passwd[50];
    	char *cmp_passwd="nulldevice";
    	int i=0;
    
    	printf("\nPassword:");
    	while((ch=getch())!='\r')
    	{
    		if(i==49)
    		{
    			printf("passwd too long");
    			exit(0);
    		}
    		passwd[i++]=ch;
    		printf("*");
    	}
    	passwd[i]='\0';
    	if(strcmp(passwd,cmp_passwd)==0)
    		printf("\nPasswds Match");
    	else
    		printf("\npasswds do not match");
    	return 0;
    }
    works fine for me amy prob with me u can contact me.

    the guy says :
    and the cursor should move ahead after every character is typed.
    clrscr() wont achieve this.
