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 ).
C99 and C11 added several additional features to C that have not been incorporated into standard C++ as of C++20, such as complex numbers, variable length arrays (complex numbers and variable length arrays are designated as optional extensions in C11), flexible array members, the restrict keyword, array parameter qualifiers, and compound literals.
Cover of the C99 standards document. C99 (previously C9X, formally ISO/IEC 9899:1999) is a past version of the C programming language open standard. [1] It extends the previous version with new features for the language and the standard library, and helps implementations make better use of available computer hardware, such as IEEE 754-1985 floating-point arithmetic, and compiler technology. [2]
CH supports the 1999 ISO C Standard (C99) and C++ classes. It is a superset of C with C++ classes. Several major features of C99 are supported, such as complex numbers, variable length arrays (VLAs), IEEE-754 floating-point arithmetic, and generic mathematical functions. The specification for wide characters in Addendum 1 for C90 is also supported.
C99 offered variable-length arrays as an alternative stack allocation mechanism – however, this feature was relegated to optional in the later C11 standard. POSIX defines a function posix_memalign that allocates memory with caller-specified alignment.
"I’m often asked if I knew it would work out. The truth is I didn’t." Ash Jurberg shares the story of meeting his wife in an essay for TODAY.com.
Flexible array members were officially standardized in C99. [4] In practice, compilers (e.g., GCC , [ 5 ] MSVC [ 6 ] ) provided them well before C99 was standardized. Flexible array members are not officially part of C++ , but language extensions [ 7 ] are widely available.
