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 ).
variable-length arrays (although subsequently relegated in C11 to a conditional feature that implementations are not required to support) flexible array members; support for one-line comments beginning with //, as in BCPL, C++ and Java; new library functions, such as snprintf; new headers, such as <stdbool.h>, <complex.h>, <tgmath.h>, and ...
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.
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.
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 introduced several new features, including inline functions, several new data types (including long long int and a complex type to represent complex numbers), variable-length arrays and flexible array members, improved support for IEEE 754 floating point, support for variadic macros (macros of variable arity), and support for one-line ...

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.
