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