Line Breaks in String Literals

String literals may span many lines. The line breaks do not need to be
escaped in any way. They are replaced by the character
string. This extension is not supported in C++ mode. The extension is not
compatible with many dialects of C including ANSI/ISO C89 and C99.
However, it is useful in
non-portable.

Arithmetic on Pointers to Void and Pointers to Functions

Addition and subtraction is allowed on pointers to
functions. The result is as if the operands had been cast to pointers to
. The
char sizeof

Cast to Union

A type cast can be used to create a value of a union type, by casting a value
of one of the unions member's types.

Ranges in Case Labels

A consecutive range of values can be specified in a single case, by separat-
ing the first and last values of the range with .... For example,
case 200 ... 300:

Declarations mixed with Code

In C mode the compiler will accept declarations in the middle of code as
in C99 and C++. This allows the declaration of local variables to be placed
at the point where they are required. Therefore, the declaration can be
combined with initialization of the variable.
