This is a list of operators in the C and C++ programming languages.. All listed operators are in C++ and lacking indication otherwise, in C as well. Some tables include a "In C" column that indicates whether an operator is also in C. Note that C does not support operator overloading.
Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter.Unlike human-readable [1] source code, bytecodes are compact numeric codes, constants, and references (normally numeric addresses) that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of ...
In C and C++, even if two pointers compare as equal that doesn't mean they are equivalent. In these languages and LLVM , the rule is interpreted to mean that "just because two pointers point to the same address, does not mean they are equal in the sense that they can be used interchangeably", the difference between the pointers referred to as ...
However, do note that a shift operand value which is either a negative number or is greater than or equal to the total number of bits in this value results in undefined behavior. This is defined in the standard at ISO 9899:2011 6.5.7 Bit-wise shift operators. For example, when shifting a 32 bit unsigned integer, a shift amount of 32 or higher ...
In C expressions, an identifier representing an array is treated as a constant pointer to the first element of the array, thus, given the declarations int a[10] and int *p; the assignment p = a is valid and causes p and a to point to the same array. As the identifier a represents a constant address, a = p is not valid, however.
two objects being equal but distinct, e.g., two $10 banknotes; two objects being equal but having different representation, e.g., a $1 bill and a $1 coin; two different references to the same object, e.g., two nicknames for the same person; In many modern programming languages, objects and data structures are accessed through references. In ...
Most C code can easily be made to compile correctly in C++ but there are a few differences that cause some valid C code to be invalid or behave differently in C++. For example, C allows implicit conversion from void * to other pointer types but C++ does not (for type safety reasons).
P-code is a name for several of Microsoft's proprietary intermediate languages. They provided an alternate binary format to machine code. At various times, Microsoft has said P-code is an abbreviation for either packed code [7] or pseudo code. [8] Microsoft P-code was used in Visual C++ and Visual Basic.
