adding an incremental value to the end of a variable

i'm not sure if correct terminology, making keypad lock cycles through 10 pin numbers, once password1 has been used password2 active code, when used password3 active code , on.


the basic idea add integer (i) end of password, when correct pw entered ++i code looking password(i) 6 next time = 7 code password7.

i cant find way add integer value end of 'password' void check password method.

code snippet

code: [select]

password password =   password ("123456");
password password1 =  password ("695847");
password password2 =  password ("176234");
password password3 =  password ("951086");
password password4 =  password ("986510");
password password5 =  password ("284396");
password password6 =  password ("084763");
password password7 =  password ("412763");
password password8 =  password ("407195");
password password9 =  password ("274069");
password password10 = password ("074859");


void checkpassword() {
   if (password(i).evaluate()){   // check pass code 0 10
          serial.println(" ok."); 
          ++;                // add 1 every time correct pw used
          if (i == 10) = 0;  // reset 0 when 10 codes used
       } else {
      serial.println(" wrong passwowrd!");
   }



this problem
if (password(i).evaluate()){   // check pass code 0 10

i have tried password + (i) , few other formats no luck yet

full code

code: [select]

password password1 =  password ("695847");

password.set(newpassword);
   resetpassword();
   serial.print("password changed ");
   serial.println(newpasswordstring);
}
 
//void resetpassword() {
   //do resetpassword
//}


any appreciated!

it wouldn't good, anyway. names not exist @ run time. addresses do, , stored in array if created array of password objects.
