    Asterisked input

    When you get input throught the cmd, using cin>>, how can I get the input to be all asterisks instead of the actual letters being typed?

    If you mean a password-like effect, I know that you can use getch() in a loop and output '*' through cout every time.

    #edit: getch() is from conio.h. But it may or may not work depending on the compiler.

    There isn't any standard way to do this. getch() is your best bet, but otherwise, you probably need a GUI which you can control.
    The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.

    I think that there may be a bit mask function that you can use.

    Not quite sure you may want to look into this.

    You may also want to try these various methods of limiting what the user inputs ( ex. number of characters, or the validation character ) :

    #include <iostream> 
    #include <conio.c> 
    using namespace std;
    int main()
    char ch;
    char ch2;
    cout << "Your password ONE should end with an asterisk (*).\n";
    cout << "Enter your password :\n>> ";  
    while (ch = getch() != '*')
        cout << "*";
    cout << "\n\n\nYour password TWO should be 8 characters long.\n";
    cout << "Enter your password :\n>> ";
    for(int x = 0; x < 8; x++)
    ch2 = getch();
    cout << "*";
    cout << endl << endl << endl;
      return 0;

    I couldn't get '\n' to replace '*' successfully. If anyone knows why, share your knowledge !
