As your build your model, there will be an executable created for the model. There are many ways to log your C code output.You can add To workspace or log the output(http://www.mathworks.com/access/helpdesk/help/toolbox/simulink/ug/f11-46877.html). If you had this setting and build the model, and run the executable in the matlab. Output will be logged in the mat file. You can compare the model output and output in the mat file obtained from the C code.
