Unix is an operating system, and C is a programming language. It just so happens that Unix is written in the C language...
Unix was created first. The C programming language was created for Unix.

There is very little difference in the C compiler between Unix and Linux; in some cases (the gcc compiler) it is the same. The differences come in when using system calls; some system calls do not exist in Unix or Linux, although most do. The program I work on compiles the same way (for the most part) between all commercial versions of Unix and several variants of Linux. In other words, the code is fairly portable across platforms.
c is a both high and low level language but pascal is a low level language only
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 has no bearing on the C language; it is cross-platform. There is no select/case in C, you probably meant switch/case. However, a switch/case is a conditional jump while a nested loop is a loop within a loop. Besides the C language they have nothing in common with each other.
Unix is primarily written in the C language, with some small snippets of assembler code for low level bootstraps.

The C and C programming languages are one and the same. There is no difference between those languages.
There is no such thing as 'unix C++'.
You can write, compile and execute C-programs in both DOS and Unix, if that's what you meant.
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.
