Write a program in c++ which show password as Stars or Dots

1. Convert Password into Stars

2. Convert Password into Dots
3. Convert Password into Character 

Structure of the problem Requirements

understanding program requirement completely mean your problem is almost solved.In this Problem we
need a coating type logic to hide our words and show some stars or dots instead of password.Here
we take the ASCII value of the integer and alphabet and then concatenate them into string.
At the end of the code an output of the code is given with Screen Shoots,you try it match it
with out and practice it ....

Source Code 

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

using namespace std;

int main(int argc, char *argv[])
      string password;
cout<<endl<<"ENTER PASSWORD : \n\n";
char c = ' ';
  while(c != 13)          
        c = _getch();         //Command for Cin but it recieve as a single digit and Proceed it
            if(c==13)                   // There is no character in 13  
if(c==8)           //There is no character in 13
                    if(password.size()!=0)  //There is still no character but if any it eliminate it    
                    cout<<"\b \b";
                    password.erase(password.size()-1); // By the decrement of 1
                    if((c>47&&c<58)||(c>64&&c<91)||(c>96&&c<123))  //ASCii code for integer and alphabet
                    password += c;       //All the word are concatenate in the String password
        cout << "*";        //Now On Screen all the words are display as a *
        cout<<endl<<endl<<"Your Password: "<<password<<endl<<endl;  // Again your password shown in word
    return 0;

Output of the Program
