Passwords/keys

When you type a key or pass, how can you make it so it displays as ******

Thanks

Code:

---

  //ENTERING PASSWORD
  //DECLARE USERPASSWORD[] AND SET IT ALL TO '\0'
  int u = 0;
  char a ;
  while (1){
      a=getch();
      if (int(a)==13){    //13 = enter
        userpassword[u]='\0';
        break;
      }
      if (int(a)==8){                          //8 = backspace
        userpassword[u-1]='\0';
        u--;
        putchar('\b');
        putchar(' ');
        putchar('\b');
      }
     
      else {
        printf("*");
        userpassword[u]=a;
        u++;
      }
  }

This would be good to put on the faq if it isnt alerady there.

Actually I was able to cut that down a few lines.

Code:

---

  //ENTERING PASSWORD
  //DECLARE USERPASSWORD[] AND SET IT ALL TO '\0'
  int u = 0;
  while (1){
      char a=getch();
      if (int(a)==13){                        //13 = enter
        userpassword[u]='\0';
        break;
      }
      else if (int(a)==8){                          //8 = backspace
        userpassword[--u]='\0';
        putchar('\b',' ',\b');
      }
     
      else {
        printf("*");
        userpassword[u++]=a;
      }
  }

that's bad programming...

try converting most of the if statements to a switch function:

example:

int x;
cin>>x;
switch(x)
{
case 0: cout<<"hey, you entered a zero... "; break;
default: cout<<x; break;
}
...

Why is it bad? I agree that if if-else statements get too big, they are unreadable, but in this case an if-else will do. According to my comp sci teacher, switch statements are slower and sort of clunky. I don't see a point to a switch here. Actually I found another error. I'll edit my previous post.

could you possibly write the code for C++, cuz printf("blah blah").. isnt that C? yea im a noob...

Printf is C, but it can also be used in C++. I was using cout but it was giving me problems so I used printf. The rest is pure C++, except for maybe putchar, that may be C. I never learned C so I don't know.

I'm a noob too, don't worry about it.

Tim...The printf and putchar are giving me errors, the error message is call to undefined function, i changed printf to cout and that worked but putchar is still giving me an error.

my bad, i forgot about #include <stdio.h> hehe

why not just make your password *****? saves time...
