The C language has implementations for all popular platforms, including Unix.
Unix was created first. The C programming language was created for Unix.
UNIX was programmed in C.
Unix is primarily written in the C language, with some small snippets of assembler code for low level bootstraps.
The C programming language was originally created for Unix. Unix, and most other Unix-like systems such as Linux, are written almost entirely in C.
You can write, compile and execute C-programs in both DOS and Unix, if that's what you meant.
C. Schirmer has written: 'Programming in C for UNIX' -- subject(s): C (Computer program language), UNIX (Computer file)
The Unix operating system. The first versions of the Unix operating system were written in the "B" language, and later written in "C", which was invented in order to develop Unix on the PDP-11 machine.
Unix was rewritten in the C Programming language and not in assembly language. The migration from assembly language to the higher-level language C resulted in much more portable software, requiring only a relatively small amount of machine-dependent code to be replaced when porting Unix to other computing platforms.

its UNIX I think :)
Unix was developed primarily using the C language; there may be a small amount of assembler/machine code used in the boot process as well.
C mainly, with a few Assembly inserts.
In UNIX: use function chmod
