   • Define 16 bit integer in C

     Top Answer

     Answered Mar 23, 2012 · 43 votes

     That means int16_t is defined as short on your machine, not all machines.

     Just use the int16_t where you absolutely need a 16bit integer type; it will be defined as appropriate on all platforms that provide stdint.h (which should be all that support C99, or cstdint for C++).

     [Edit] To clarify, the "stdint.h" header file is provided by the C (or C++) compiler, so its contents will likely vary per compiler, version, system, CPU architecture, etc. That is, the authors of the compiler suite know exactly what types have what sizes on which systems. Looking at that file on just one system only tells you about the definitions for a particular version of a particular compiler on a particular OS on a particular architecture (e.g. GCC 4.2 on Darwin x86_64, or Visual Studio on WinNT Alpha, or ICC on Solaris IA32, etc). Some systems, especially embedded ones, might have different type sizes, so a short might not always be 16 bits, and the compiler would know the right size to use for that bit length.

     If you look at the file stdint.h on another system the definitions might be different, or they might be the same - but its purpose is to provide the definitions for integer types of guaranteed bit lengths.

   • Bit Stuffing in Computer Network

     The data link layer is responsible for something called Framing, which is the division of stream of bits from network layer into manageable units (called frames). Frames could be of fixed size or variable size. In variable-size framing, we need a way to define the end of the frame and the beginning of the next frame. 

     Bit stuffing is the insertion of non information bits into data. Note that stuffed bits should not be confused with overhead bits. 

     Overhead bits are non-data bits that are necessary for transmission (usually as part of headers, checksums etc.).

     Applications of Bit Stuffing –

     • synchronize several channels before multiplexing
     • rate-match two single channels to each other
     • run length limited coding

     Run length limited coding – To limit the number of consecutive bits of the same value(i.e., binary value) in the data to be transmitted. A bit of the opposite value is inserted after the maximum allowed number of consecutive bits. 

     Bit stuffing technique does not ensure that the sent data is intact at the receiver side (i.e., not corrupted by transmission errors). It is merely a way to ensure that the transmission starts and ends at the correct places. 

     Disadvantages of Bit Stuffing:

     • The code rate is unpredictable; it depends on the data being transmitted. 
     • The stuffed bits do not contain any information.

   • #define in #define; what happens in the preprocessor?

     Top Answer

     Answered Dec 08, 2013 · 6 votes

     The C standard has a special terminology for how macros are expanded.

     Macro names are, in effect, stored in a big table of "all macros defined at this time". Each table entry "macro name" on the left (and any arguments in the middle) and "expansion token-stream" on the right.

     When a macro is to be expanded (because it occurs in some non-preprocessor line, or in a position in a preprocessor line in which it must be expanded -- e.g., you can #define STDIO <stdio.h> and then #include STDIO), the table entry is "painted blue", and then the replacement token-stream is read (with argument expansion as also dictated by the standard).

     If the replacement token-stream contains the original macro name, it no longer matches, because the "blue paint" covers up the name.

     When the replacement token-stream has been fully handled, the "blue paint" is removed, re-exposing the name.

     Thus:

     #define X 5-

     adds X: (no arguments), 5 to the table.

     Then:

     #define Y X-

     adds: Y: (no arguments), X to the table.

     Somewhere later in the file, you might have an occurrence of the token Y. Assuming neither of the above have been #undefed (removed from the table), the compiler must first "paint the table entry for Y blue" and replace the token Y with the token X.

     Next, the compiler must "paint the table entry for X blue" and replace the token X with the token 5.

     The token 5 is not a preprocessor macro name (it can't be by definition) so the token 5 passes beyond the reach of the preprocessing phase. Now the "blue paint" is removed from the X table entry, as that's done; and then the "blue paint" is removed from the Y entry, which is also done.

     If you were to write instead:

     #define Y Y, Y, Y, the letter is called Y!-

     then the sequence, on encountering a later token Y, would be:

     • paint entry for Y blue
     • drop in replacement token sequence: Y , Y , Y , the letter is called Y !
     • check each replacement token in the table -- since Y is painted blue those don't match, and , cannot match, so those are all passed on to the rest of the compiler; the, letter, is, and called must be checked but are probably not in the table and hence passed on; Y is still painted blue so does not match and is passed on, and ! cannot match and is passed on.
     • remove blue paint, restoring the expansion
