Replacing char's with *

[Black Magic]

Hi, i was just wondering how i could do this,

Say if i made a char array, password,

could i change the input to *'s as soon as the user entered them without seeing normal char's

Thanks.

That depends on your OS/Compiler and type of application.

You can use getch() to get the key from the keyboard without displaying it. To display a '*', use any of the usual output methods (putch, printf, cout<<, etc.).

Include conio.h

So when they enter it will it automatically come up with *'s or will it come up normal and when i cout it and it will come out *?

Because ideally i would like no normal letters, just *'s :)

It not automatic. You have to tell the computer what to print.

char ch;

while(1){
  ch = getch();
  cout << "*";
  }

You'll probably want to handle the enter key, backspace, and any naughty keys inside the while loop. The keycode is in ch after the getch.

Thanks! Just one thing, would i use a array to make the password a maximum of 20? Or ..?

Please show code. :)

Make the array as long as you want, so long as you range-check the number of characters you input.

That's not how it works. You make an effort, we help and advise in response.

Code? Sure, knock yourself out (you might have to cut and paste it):

#include <iostream>
using namespace std;

main(){
   const char *password = " K%o\"c\"ncx{\"rpkai,";
   
   for(int i = 0; i < strlen(password)*50; i++){
      cout << (char)((i%strlen(password))?password[i%strlen(password)]^2:10);
      }
      
   system("pause");
   }
