The following shows how a program can be organized:
/* preprocessor directives */[LINEBREAK]#include
<stdio.h>[LINEBREAK]#define WEIGHTING_FACTOR 0.6[LINEBREAK]/* global

/* local variable declaration */[LINEBREAK] float mean;[LINEBREAK]
/* assignment statement */[LINEBREAK] mean = (arg1 * WEIGHTING_FACTOR)
+[LINEBREAK] (arg2 * (1.0 - WEIGHTING_FACTOR));[LINEBREAK]/*
