  2. Pointer (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Pointer_(computer_programming)

    A pointer a pointing to the memory address associated with a variable b, i.e., a contains the memory address 1008 of the variable b.In this diagram, the computing architecture uses the same address space and data primitive for both pointers and non-pointers; this need should not be the case.

  3. Type punning - Wikipedia

    en.wikipedia.org/wiki/Type_punning

    On many common platforms, this use of pointer punning can create problems if different pointers are aligned in machine-specific ways. Furthermore, pointers of different sizes can alias accesses to the same memory, causing problems that are unchecked by the compiler. Even when data size and pointer representation match, however, compilers can ...

  4. Function pointer - Wikipedia

    en.wikipedia.org/wiki/Function_pointer

    The C and C++ syntax given above is the canonical one used in all the textbooks - but it's difficult to read and explain. Even the above typedef examples use this syntax. However, every C and C++ compiler supports a more clear and concise mechanism to declare function pointers: use typedef, but don't store

  5. Factorion - Wikipedia

    en.wikipedia.org/wiki/Factorion

    Let be a natural number. For a base >, we define the sum of the factorials of the digits [5] [6] of , :, to be the following: ⁡ = =!. where = ⌊ ⁡ ⌋ + is the number of digits in the number in base , ! is the factorial of and

  6. Reference (computer science) - Wikipedia

    en.wikipedia.org/wiki/Reference_(computer_science)

    However, also due to this relationship, pointers require a strong understanding by the programmer of the details of memory architecture. Because pointers store a memory location's address, instead of a value directly, inappropriate use of pointers can lead to undefined behavior in a program, particularly due to dangling pointers or wild pointers.

  7. Factorial - Wikipedia

    en.wikipedia.org/wiki/Factorial

    The simplicity of this computation makes it a common example in the use of different computer programming styles and methods. [76] The computation of ! can be expressed in pseudocode using iteration [77] as define factorial(n): f := 1 for i := 1, 2, 3, ..., n: f := f * i return f

  8. Smart pointer - Wikipedia

    en.wikipedia.org/wiki/Smart_pointer

    Smart pointers typically keep track of the memory they point to, and may also be used to manage other resources, such as network connections and file handles. Smart pointers were first popularized in the programming language C++ during the first half of the 1990s as rebuttal to criticisms of C++'s lack of automatic garbage collection. [1] [2]

  9. Compile-time function execution - Wikipedia

    en.wikipedia.org/wiki/Compile-time_function...

    In C++11, this technique is known as generalized constant expressions (constexpr). [2] C++14 relaxes the constraints on constexpr – allowing local declarations and use of conditionals and loops (the general restriction that all data required for the execution be available at compile-time remains).
