Emacs indentation for multi-level nesting of C code

I'm completely new to emacs (mostly used vim and eclipse/netbeans etc.) I was playing with multi-level nesting of C code and wrote a sample code in emacs to test how it indents codes where nesting is way too deep (not real life code though).

int foo()
{
    if (something) {
        if (anotherthing) {
            if (something_else) {
                if (oh_yes) {
                    if (ah_now_i_got_it) {
                        printf("Yes!!!\n");
                    }
                }
            }
        }
    }
}

This looked exactly like this as I typed in emacs and saved it. But opening it on a different text editor showed the actual text saved is this:

int foo()
{
    if (something) {
    if (anotherthing) {
        if (something_else) {
        if (oh_yes) {
            if (ah_now_i_got_it) {
            printf("Yes!!!\n");
            }
        }
        }
    }
    }
}

So I was wondering is there any way in emacs to save the text the way it actually displays?

My current c-default-style is set to "linux".

EDIT:

Ok, I was using Notepad++/Vim to view the file saved by emacs and it showed that "wrong" indentation, but looks like, opening with good old notepad (or even doing a cat file.c) shows the correct indentation as displayed by emacs. Will try the other approaches mentioned here. Thanks!

Try using spaces instead of tabs for indentation. Add the following to your init.el:

(setq-default indent-tabs-mode nil)

This will make all buffers use spaces by default. You will want to add the following exception for makefiles:

(add-hook 'makefile-mode-hook (lambda () (setq indent-tabs-mode t)))
