If the size of the array is indicated by*instead of an expression, the variable length array is considered to be of unspecified size. Such arrays are considered complete types, but can only be used in declarations of function prototype scope. A variable length array and a pointer to a varia...
Variable-length arrays,PolarDB:The number of elements of a variable-length array ranges from zero to the declared maximum length. TYPE type_name IS VARRAY '(' number ')' OF datatype [NULL | NOT NULL] ';'ExamplesSee the following ex...

A variable length array cannot be initialized. Note: In C++ applications, storage allocated for use by variable length arrays is not released until the function they reside in completes execution. A variable length array can be the operand of a sizeof expression. In this case, the operand is...
Variable-length arrays (VLAs) are neither part of Cilk Plus nor part of standard C++. The Intel compiler supports a subset of VLAs in C++ mode and g++ supports a smaller subset, but this support is not considered part of Cilk Plus, though I agree that it does make a nice combination...
When a variable length array (C99 supported) is declared, and error: "expression must have a constant value" is raised. To Reproduce #include<stdio.h>intmain(void) {inti,n;printf("How many numbers do you want to reverse? ");scanf("%d",&n);inta[n];printf("Enter &d numbers: ",n...
A record structure can contain multiple variable-length arrays; however, the fields that define the size of the arrays (the ODO or REFER “objects”) must all appear in the record prior to the first variable-length array item, or, in the case of PL/I REFER length, prior to the first ...
It seems that I can use OpenMP together with CilkPlus array notation on variable length arrays, but not _Cilk_for. This is under the Intel compiler with build 13.1.2.183. I get messages like: junk.cpp(10): error: a variable captured by a lambda cannot have a type involving a variable...

Because variable-length arrays have no explicit syntax in C, these declarations are actually compiled into structure definitions, signified by struct. For example, the heights declaration is compiled into the following structure: struct { u_int heights_len; /* # of items in array */ int *hei...
