  2. Arithmetic shift - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_shift

    It does not specify the behaviour of the right shift operator in such circumstances, but instead requires each individual C compiler to define the behaviour of shifting negative values right. [note 8] Like C, C++ had an implementation-defined right shift for signed integers until C++20. Starting in the C++20 standard, right shift of a signed ...

  3. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    All the operators (except typeof) listed exist in C++; the column "Included in C", states whether an operator is also present in C. Note that C does not support operator overloading. When not overloaded, for the operators && , || , and , (the comma operator ), there is a sequence point after the evaluation of the first operand.

  4. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    The C-family of languages lack a rotate operator (although C++20 provides std::rotl and std::rotr), but one can be synthesized from the shift operators. Care must be taken to ensure the statement is well formed to avoid undefined behavior and timing attacks in software with security requirements. [ 6 ]

  5. Bitwise operations in C - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operations_in_C

    The symbol of right shift operator is >>. For its operation, it requires two operands. It shifts each bit in its left operand to the right. The number following the operator decides the number of places the bits are shifted (i.e. the right operand). Thus by doing ch >> 3 all the bits will be shifted to the right by three places and so on.

  6. Maximal munch - Wikipedia

    en.wikipedia.org/wiki/Maximal_munch

    Another example, in C++, uses the "angle bracket" characters < and > in the syntax for template specialization, but two consecutive > characters are interpreted as the right-shift operator >>. [4] Prior to C++11, the following code would produce a parse error, because the right-shift operator token is encountered instead of two right-angle ...

  7. Logical shift - Wikipedia

    en.wikipedia.org/wiki/Logical_shift

    The programming languages C, C++, and Go, however, have only one right shift operator, >>. Most C and C++ implementations, and Go, choose which right shift to perform depending on the type of integer being shifted: signed integers are shifted using the arithmetic shift, and unsigned integers are shifted using the logical shift.

  8. List of CIL instructions - Wikipedia

    en.wikipedia.org/wiki/List_of_CIL_instructions

    Shift an integer right (shift in sign), return an integer. Base instruction 0x64 shr.un: Shift an integer right (shift in zero), return an integer. Base instruction 0xFE 0x1C sizeof <typeTok> Push the size, in bytes, of a type as an unsigned int32. Object model instruction 0xFE 0x0B starg <uint16 (num)> Store value to the argument numbered num.

  9. C alternative tokens - Wikipedia

    en.wikipedia.org/wiki/C_alternative_tokens

    The above-mentioned identifiers are operator keywords in the ISO C++ programming language and do not require the inclusion of a header file. [3] For consistency, the C++98 standard provided both <iso646.h> and a corresponding <ciso646>.
