warning: variable length arrays in C++ are a Clang extension [-Wvla-cxx-extension] 讨论使用变长数组可能带来的问题和风险 类型安全:变长数组破坏了C++的类型安全原则,因为数组的大小在运行时确定,可能导致越界访问等安全问题。 可移植性:由于变长数组不是C++标准的一部分,使用它的代码可能无法在不同的编译器...

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 are optionally available in C since C99 and mandatory since C23. In C++, variable-length arrays are available in non-standard extensions (for example, in GCC). Instead of them, you can use the non-standard alloca function to allocate memory on a stack or the standard...

Variable Length Arrays (VLAs) are not currently supported in Visual C++.VLAs are part of C99 which is gradually being added to VC++ in each new release.C99 library support in Visual Studio 2013 http://blogs.msdn.com/b/vcblog/archive/2013/07/19/c99-library-support-in-visual-studio...
Because variable-length arrays have no explicit syntax in C, these declarations are compiled intostructdeclarations. For example, theheightsdeclaration compiled into the followingstruct: struct { u_int heights_len; /* # of items in array */ int *heights_val; /* pointer to array */ } heights...
Use this check to detect negative array bounds. Variable-length arrays with a negative length have undefined behavior, and may cause stack corruption. Available in Xcode 9 and later. Negative variable-length array bounds in C In the following code, the call to theinvalid_index_returning_function...
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...
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...
