A C++ Question ? How to read a 2 letter character in an input.?

I have to create a program that reads in characters until the user enters the correct two- character sequence= (cs) to open door.





Sample Data:


cs = Door opens





ccs=Door opens





fkcds=Door doesn't open





kasfcsgd=Door opens





I have to use While Loop. but I need Answers what to put in -





My code:


/*====================================...





#include %26lt;iostream.h%26gt;





void main()


{


char ch;


int done;





cout %26lt;%26lt; endl %26lt;%26lt; "You have before you a closed door." %26lt;%26lt; endl;





while(done)


{


cout%26lt;%26lt;"Enter a sequence of letters: ";


cin%26gt;%26gt;ch;





if()


}





cout %26lt;%26lt; "The door opens. Congratulations!" %26lt;%26lt; endl;


}





/*====================================...





It is not Finished, It is just a shell I made to help.

just add another variable...one that keeps track of a "c" and one for an "s"...the better way is to use strcmp(), but be careful of hidden null characters at the end which may or may not be an issue.
