[C++] How to make hashed password input

Hello, in this post I will show yoy how to make a function

that asks for a password and when loading it covers the typed text with stars.

So, the first thing we do is write the skeleton of the function:

#include <iostream>
#include <conio.h>
using namespace std;
string password(){
}
int main(){
    password();
}

Ok, now lets write the code inside the password () function.

string password(){
    char key;
    int code;
    string pass = "";
    cout << "Enter password: ";
    do{
        key = getch();
        pass = pass + key;
        cout << "*";
        code = static_cast < int >( key );
    } while( code != 13 );
    cout << endl;
    return pass;
}

So there are three variables here.

Name	Type	Content
Key	Char	Currently entered character
Code	Int	The code of the current character (ASCII)
Pass	String	The entire loaded password (created from all entered characters)

Loading characters works as follows: The entire program should look like this:

#include <iostream>
#include <conio.h>

using namespace std;

string password(){
    char key;
    int code;
    string pass = "";
    cout << "Enter password: ";
    do{
        key = getch();
        pass = pass + key;
        cout << "*";
        code = static_cast < int >( key );
    } while( code != 13 );
    cout << endl;
    return pass;
}

int main(){
    cout << "Your password is: " << password();
    return 0;
}

And the effect!
