You can do it, but not with standard C or C++. You need to have more control over the terminal than the languages proper have. What OS and compiler are you using?

Actually not command......

It is "code"

Example like
int = integer
char = character

I want the code to block the user from key in the more space from limitation that programmed

I should I add to the code?
Can you give me the simplest example?

Example
This is program only allow user to input 6 character only to create a password

The user want to input password as Micheal

Password:

He type Micheal

Passwoord:Michea

He cannot input the letter "l"
Except he can press "Enter" and "Backspace"

If he press "Enter" mean his password is "Michea"
Or otherwise He got to change his password

How it can be don't?

If you are talking about stopping the actual physical keyboard characters from appearing within the command window while the user is typing, then please refer to Voodoo Doll's post above...I don't believe it can be dome with C++, you would need to access the command window application itself to modify it's behaviour.

If, however, you are talking about duplicating that behaviour in a windows type application that you built yourself, then it is easier.
