There are two ways:  
1) if you have mathematica 2.2.2 or later, you can use mathlink.
2) you can use the command Run to run a program.  Have the c program use
a data file as input and output its results to a file.  Mathematica can
edit and set up the input file, then read the output when your c program
is done.
