I'm making an ATM interface on C++ for a school project of my friend. How can i change the PIN number into asterisks "*"? P.S. the pin number codes are in the MAIN. thanks :D

In the future, it would be worth posting a smaller code sample that demonstrates your problem instead of a giant blob of code with your problem buried somewhere inside — Krease, Oct 06 '14 at 04:30
Was it really necessary to dump five pages of code into the question, when you could have just asked, "How can I read a number from `cin` but display asterisks instead of the characters entered?" — Tom, Oct 06 '14 at 05:33

You can use getch() like this:

int i=1;
cout<<"\n\n\n\t\t\t\tEnter your PIN: ";
while((p=getch()) != '\n' && p==i) {
    i++;
    cout<<"*";
}
if(i==5)   
    transaction();            
else {        
    clrscr();         
    cout<<"\n\n\n\t\t\t\t   Wrong PIN!";         
    cout<<"\n\n\t\t\t    Please get your card.";         
}

Or like this:

int i=0,pin[4]={0};
cout<<"\n\n\n\t\t\t\tEnter your PIN: ";
while((pin[i]=getch()) != '\n' && i<4) {
    i++;
    cout<<"*";
}
if(pin[0]==1 && pin[1]==2 && pin[2]==3 && pin[3]==4)   
    transaction();            
else {        
    clrscr();         
    cout<<"\n\n\n\t\t\t\t   Wrong PIN!";         
    cout<<"\n\n\t\t\t    Please get your card.";         
}

it doesn't work :( the first time i press a key on the keyboard, the "wrong pin! Please get your card" pops out. – Patrick Wayne Oct 06 '14 at 09:21
Did you type 1234 ? If yes,try the edited code. Accept the answer if it worked! – Spikatrix Oct 06 '14 at 09:58
"1234" already worked but when i enter a different pin it doesn't input and when i enter 1 as first digit and any number other than 2 as second digit it deletes the first digit that i entered. – Patrick Wayne Oct 06 '14 at 11:37
So tell the maximum length of the pin – Spikatrix Oct 06 '14 at 11:41
the maximum length is 4 – Patrick Wayne Oct 06 '14 at 11:43
Now try it and accept my answer if it helped ! – Spikatrix Oct 06 '14 at 11:50
when i press enter after inputing the pin the program terminates – Patrick Wayne Oct 06 '14 at 12:10
hey can i have the first codes that you've posted before editing it? i think i copied it wrong. – Patrick Wayne Oct 06 '14 at 12:17
The one starting with int or char ? – Spikatrix Oct 06 '14 at 13:13
the first one that you answered. – Patrick Wayne Oct 06 '14 at 13:38
It won't work when you enter a wrong integer. – Spikatrix Oct 06 '14 at 13:46
