Disclaimer: I am not a VI expert by any means.. but I can give you a couple of helpful pointers.

First thing you can do to make your life a bit easier is install gvim. The number 2 problem is linked to number 1, if you are not in insert mode, you must be in command mode so VI was probably interpreting it as a beginning of a command.

Where exactly did you search for programming, from which help menu?

For C/C++ programming you need to have GCC installed (I have not used Ubuntu but I am sure it must be installed on your system). Open a terminal and type

 gcc -v

This will tell you what version of gcc you have, and what configuration options it has enabled. Look for a line that reads something like --enable-languages=ada,c,c++ that will tell you what type of code you can compile and execute.

I recommend you install the package build-essential

This package will give you most packages you will need to write your C/C++ software.

i installed the package build-essential first. from there i went into synaptic package manager and slected all of the dev packages that i wanted to use, and they were installed from the cd mainly.hope this helps.so far it has only asked for the cd for the packages

Also, I want to add that the default vi installed is vim-tiny (on Ubuntu), which to be frank, is extremely poor and watered down version of vim. I would recommend installing the package vim-full instead as it will come with a lot more stuff.

Have you tried another editor, such as nedit? It is a MUCH better programming editor than vi/vim, et al. It is a GUI editor, so it won't work on a non-gui system, but it's great on any X-Windows front end. I even run it under cygwin on Windows. You should be able to install it from the Synaptic package manager. I did so on my Ubuntu laptop.

why not try some IDE for programming , there are many to try out.

My primary argument against IDE programming is that it consumes more CPU time, than it is worth to me. I can do my debugging outside a development environment, highlighting works in Gedit, and outside of an IDE you have much more control over your project (as you write your own makefiles).

I just want to remind u one silly think....u hv to pree enter after hittinf 'i' or 'a' in vi to get into the corresponding modes

Though,I like vi,I would suggest Gedit too. make sure that you have gcc available on system. Though I'm not an ubuntu user check you "install/remove programs" (as in mandriva) or Synaptic package manager (as in debian) and install gcc packages.
