You want a maze ?  Here is one:

char*M,A,Z,E=40,J[40],T[40];main(C){for(*J=A=scanf(M="%d",&C);
--            E;             J[              E]             =T
[E   ]=  E)   printf("._");  for(;(A-=Z=!Z)  ||  (printf("\n|"
)    ,   A    =              39              ,C             --
)    ;   Z    ||    printf   (M   ))M[Z]=Z[A-(E   =A[J-Z])&&!C
&    A   ==             T[                                  A]     
|6<<27<rand()||!C&!Z?J[T[E]=T[A]]=E,J[T[A]=A-Z]=A,"_.":" |"];}

It works, too !
The program first pauses to have you enter the number of lines of maze you
want, then goes about to write it (on 79 char).

Ah, before i forget: the left shift of the rand() function is implementation
specific.  Correct it if needed... (where? on the bottom left corner :-)

NOTE:  This aMAZEing program isn't mine, it's just the source on which I
learned C for the first time (indentation and comments came later :-).  As a
rough guess, this *must* be the winner of an `obfuscated c code contest'
some years ago, but i got this without reference...
If the author is listening, congratulations and apologies !
