C Constructs Supported

When writing code fragments in C, keep these guidelines in mind:

• C-style (/* comment */) and C++-style (// comment) comments are permitted. For example:

      // This code fragment creates a temporary patch
    i = i + 2;     /* Add two to i */

• You can omit semicolons if the result is not ambiguous.
   
• You can use dollar signs ($) in identifiers.
