is that a console program?
If so, then just use something similar to the following

cout<<"Enter PIN";
cin>>intPin;
if intPin==MACROPIN then 
{
  //call a fn or whatever
}
else
{
cout<<"Access Denied";
return 9;
}

Hope this is what you were looking for.

^^Why return 9?. He can call main again and ask for a password.

frnd u can use this

char a[]="password"; // U Can use ur own
char ch,b[20];
int i=0;
do
{
ch=getch();
b[i++]=ch;
cout<<"*"; // u can use ur own symbol
}while(ch!='\r') // \r has been used for Enter key
b[i-1]='\0';
if(strcmp(a,b)==0)
cout<<"correct"; //here u can use ur program
else
cout<<"access denied";
[/qoute]

Use this code which have some more advantages:

• Will allow use of Backspace
• Will not scan Tab key & function keys such as F1, F2, Home, End ... etc.

#include<string.h>

void main()
{
char c='\0', d='\0', pt[50], ps[]="ur password";
int m=0,n=0;
clrscr();

 while(c!=13)
 {
	c=getch();

	if(c==13)
	{
		for(n; n>=0 ;n--)
		{ pt[m]='\0'; m--; }

		if(strcmp(pt,ps)==0)
		{
		cout<<endl<<"Password accepted."<<endl;
		/*Use ur prog here*/
		}

		else
		cout<<endl<<"Invalid Password!";
	}

	else if(c >31 && c <127)
	{
		for(n; n>0 ;n--)
		{ pt[m]='\0'; m--; }

		pt[m]=c; m++;
	}

	else if(c == 8)
	n++;

	else
	{
	if(c!=9)
	d=getch(); cout<<"\a";
	}
 }
 getch();
}

Thx for repu.
I will do ur job but don't u think that we can just manipulate this code so that u can understand it.
If u want somewhat different then tell me, what exactly u want.
