WebMay 21, 2013 · The bit shift above has a bug: unsigned short p = (packetBuffer[1] << 8) packetBuffer[2]; if packetBuffer is in bytes (8 bits wide) then the above shift can and will turn packetBuffer into a zero, leaving you with only packetBuffer[2]; Despite that this is still preferred to pointers. To avoid the above problem, I waste a few lines of code ... WebThe bit is the most basic unit of information in computing and digital communications. The name is a portmanteau of binary digit. [1] The bit represents a logical state with one of …

In practice, char is usually 8 bits in size and short is usually 16 bits in size (as are their unsigned counterparts). This holds true for platforms as diverse as 1990s SunOS 4 Unix, Microsoft MS-DOS , modern Linux , and Microchip MCC18 for embedded 8-bit PIC microcontrollers . See more In the C programming language, data types constitute the semantics and characteristics of storage of data elements. They are expressed in the language syntax in form of declarations for memory locations See more Main types The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large … See more Structures aggregate the storage of multiple data items, of potentially differing data types, into one memory block referenced by a single variable. The following example declares the data type struct birthday which contains the name and birthday of a … See more Every data type T has a corresponding type pointer to T. A pointer is a data type that contains the address of a storage location of a … See more The C99 standard includes definitions of several new integer types to enhance the portability of programs.

An array is a collection of values, all of the same type, stored contiguously … See more WebJan 20, 2016 · As you can see, int-> short yields the lower 16 bits, as expected. Casting short to int yields the short with the 16 high bits set. However, I suspect this is implementation specific and undefined behavior. You're essentially interpreting 16 bits of memory as an integer, which reads 16 extra bits of whatever rubbish happens to be …
WebSep 23, 2008 · 6 Answers. Nope. But you can use short integers in arrays: from array import array a = array ("h") # h = signed short, H = unsigned short. As long as the value stays in that array it will be a short integer. A better and … Webbyte1 is a variable containing bit pattern 0xFF. If char is unsigned that value is interpreted as 255, if it is signed it is -128. When doing the calculation, C will extend the value to an int size (16 or 32 bits generally). This means that if the variable is unsigned and we will keep the value 255, the bit-pattern of that value as int will be ...
WebFeb 27, 2011 · 13. As schnaader said, you may be running into an overflow problem. But answering your printf question about outputting unsigned values, you want the u modifier (for "unsigned"). In this case, as Jens points out below, you want %hu: printf ("a: %hu\n", a); ...although just %u ( unsigned int, rather than unsigned short) would probably work …
