Within a Mathematica notebook, you can use functions such as CForm 
to get a get a translation of the Mathematica expression to a C expression:
f[x] = x^2;
You can also ask Mathematica to process a source or document file
written, say in C or any other languages, that includes Mathematica
code, with the Splice function. See  for an example in C.
 /The Mathematica Book/, Section 1.11.9, "Splicing Mathematica Output
into External Files"
