How do I change Indentation for C Source Code?

[Ben Robinson]

Hello,

When the Major mode is either (C) or (C++), every line of C source code
begins with 2 spaces.  Any tabs or indentation begin from that point.

When I open source code created with emacs, the code is positioned 2
spaces in, 6 spaces in, 10 spaces in, etc...  The formula would be
(spaces = 4x+2) where 'x' is the number of tabs.

When I open source code created with a Windows editor, the code is
positioned 4 spaces in, 8 spaces in, 12 spaces in, etc...  The formula
would be (spaces = 4x) where 'x' is the number of tabs.

I need to edit the emacs code to not insert the 2 spaces at the front of
every line and instead add either no spaces or a single tab to make my
code compatible between both editors.

How can I do this?

Thank you very much,
