Solaris

I am very new to solaris, i install Solaris 10 in a SunBlade 100 just a couple of weeks ago, and i'm very impresed with Solaris, i'm loving it.
The firts reason that i wanted to use Solaris is for programming, and the second reason because i've been fan of Sun Microsystems long time ago and i'm very impresed allready with the OE.

I'm new to programming also, i want to start with C, then C++, JAVA, FORTRAN, PERL, PHYTON, and some oders.

But anyway, to my problem.
I look around Solaris to see if i have sun studio but i can't find it.

I make i small program in C to see if i have a compiler installed, (i've had installed the hole Solaris 10 OE) i type this command,

# cc program.c and i get this message

/usr/ucb/cc: language optional software package not installed

i download sunstudio 11 and i installed like this

Step 1

- Download file into a scratch download directory, such as /var/tmp.

Step 2

- Unpack the archive into the /opt directory with the commands:

# cd /opt

# bzcat DOWNLOAD-DIRECTORY/sunstudio11-ii-DATE-PLATFORM.tar.bz2 | /bin/tar -xf -

If you use sh (or ksh):
% PATH=[installpath]/bin:$PATH ; export PATH
% MANPATH=[installpath]/man:$MANPATH ; export MANPATH

i try to start studio with this command

# studio & and i get this message

[2] 869
# ksh: studio: not found

Can someone let me know how to start sunstudio.

Also, i'd like some advice on what books are very good to learn Solaris very deeply, i'd like to become like a guru in Solaris.

Thank you in advanced.
