Body Files

• Properly prototype all file static functions with usefully named parameters.

• Whenever possible, make variables and functions static or place them in an anonymous namespace to reduce namespace collisions. For example:

  // file : sort.cc
  // both swap1 and swap2 are only visible in sort.cc
  static void swap1(float& f1, float& f2) { /* ... */ }
  namespace
  {
  void swap2(float& f1, float& f2) { /* ... */ }
  }
  

• Avoid global variables.

• Constants and macros definitions should be at the top of the file or, when appropriate, in an include file.

• Multiple variables of the same data type may be declared on the same line if they correspond to fields of some logical data structure.

    char *r, *g, *b;
    float x, y, z;
