A simple function that hides typed passwords in C++
In C++ console there's no way of hiding passwords at the same time we type them (I mean, our password remains visible for everyone who may sit next to us). There's a simple way to avoid this that resembles to what can be easily made in HTML or JavaScript: simply adding a cls command to clear all the console output until that moment and then popping up the same stuff but now with '*' instead.

You are wrong....see and execute the following code snippet
ResponderEliminar{
clrscr();
cout<<endl<<"Ultimate Quiz Password Authentication"
<<endl<<endl<<"Enter current password: ";
for (int i = 0; ;i++)
{
check[i] = getch();
if (check[i] == '\r')
break;
cout<<"*";
}
I myself am a programmer and your mutating encryption algorithm was really awesome and simple at the same time
I had no idea of how to do it, but your snippet works perfectly!! Thanks so much :)
EliminarThanks.....do u know some really good encryption algorithm that can be broken by school students in about an hour or so ?
EliminarDear Ashutosh, sorry for the delay.
EliminarMaybe you could use a very simple encryption algorithm which basically consists on mapping all characters into the numerical ASCII code, then adding to each one 'k' (being k an integer).
Thank you very much.
