    char x[10];

    for(int i=0; i<10;i++){
        x[i]=getch();
        cout<<"*";

        if(x[i]=='\r') //check if enter key is pressed
            break;

        else if(x[i]=='\b'){

            if(i==0)
                cout<<"\b"<<" "<<"\b";
            else if(i>=1){
                x[i-1]='\0';//make the previous byte null if backspase is pressed
                i=i-2;
                cout<<"\b"<<" "<<"\b\b"<<" "<<"\b";
            }

         }
    }

    cout<<endl<<"the password is  :"<<x<<endl;
    system("pause");
