ASML C Coding Standard

Rule: 6.8.a

Synopsis:	All control statements shall be fully brace enclosed. This means that all "if", "while", "for", "do" and "switch" statements are followed by a brace-enclosed compound statement.
Language:	C
Severity Level:	5
Category:	Statement and Blocks

Description:

Justification

By using braces a visible grouping of statements is created. Programming errors can be caused when the body of a control statement without braces is expanded from one statement to many.

Example 1

if (...)
   if (...) /* WRONG */
   {
      ...
   }
else /* This "else" belongs to the second "if" and not to the first "if".*/
{ 
   ...        
}

Example 2

if (...)
{ /* RIGHT */
   if (...)
   {
      ...
   }
}
else
{
   ...
}
