Coding Style

Use same indent style with existing code. One indentation is made by 4 spaces. No tabs are used because their width depends on environments.

• indentation by 4 spaces.

 not:
   if (a < b) {
    return a;
   }
 but:
   if (a < b) {
       return a;
   }

• space after if, while and for.
• braces on if, while and for line.
• no space on inner side of parentheses.
• spaces on both sides of binary operators(<, >, ==, !=, =, +=, etc.).
• no space between unary operators(++, --, !, etc.) and their operands.

 not:
   if( a<b )
   {
       return a;
   }
   else
   {
       a ++;
       return b;
   }
 but:
   if (a < b) {
       return a;
   } else {
       a++;
       return b;
   }

If you are using emacs, add the following code to your .emacs.

(c-add-style
 "ruby"
 '("bsd"
    (c-basic-offset . 4)
    (tab-width . 4)
    (c-offsets-alist
     (case-label . 0)
     (label . 0)
     (statement-case-intro . 4))))

It help you to indent the code in emacs because all C source files include the following line.

 /* -*- c-file-style: "ruby"; indent-tabs-mode: nil -*- */
