  2. sizeof - Wikipedia

    en.wikipedia.org/wiki/Sizeof

    sizeof is a unary operator in the programming languages C and C++. It generates the storage size of an expression or a data type , measured in the number of char -sized units. Consequently, the construct sizeof (char) is guaranteed to be 1 .

  3. Flexible array member - Wikipedia

    en.wikipedia.org/wiki/Flexible_array_member

    The sizeof operator on such a struct gives the size of the structure as if the flexible array member were empty. This may include padding added to accommodate the flexible member; the compiler is also free to re-use such padding as part of the array itself.

  4. Compatibility of C and C++ - Wikipedia

    en.wikipedia.org/wiki/Compatibility_of_C_and_C++

    The C and C++ programming languages are closely related but have many significant differences. C++ began as a fork of an early, pre-standardized C, and was designed to be mostly source-and-link compatible with C compilers of the time.

  5. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    The C language specification includes the typedef s size_t and ptrdiff_t to represent memory-related quantities. Their size is defined according to the target processor's arithmetic capabilities, not the memory capabilities, such as available address space. Both of these types are defined in the <stddef.h> header (cstddef in C++).

  6. Variable-length array - Wikipedia

    en.wikipedia.org/wiki/Variable-length_array

    In computer programming, a variable-length array (VLA), also called variable-sized or runtime-sized, is an array data structure whose length is determined at runtime, instead of at compile time. [1] In the language C, the VLA is said to have a variably modified data type that depends on a value (see Dependent type).

  7. Talk:Sizeof - Wikipedia

    en.wikipedia.org/wiki/Talk:Sizeof

    I think the article was written solely with C89 in mind. Variable length arrays are not mentioned. In such a case, sizeof(a[n]) is evaluated at run-time, so it's not a compile-time constant in all cases. Another important use is mentioned either: sizeof(a) / sizeof(a[0]) is used to calculate the number of elements in an array.

  9. offsetof - Wikipedia

    en.wikipedia.org/wiki/Offsetof

    C's offsetof() macro is an ANSI C library feature found in stddef.h. It evaluates to the offset (in bytes) of a given member within a struct or union type, an expression of type size_t . The offsetof() macro takes two parameters , the first being a structure or union name, and the second being the name of a subobject of the structure/union that ...
