Data structures known as variable sized arrays have a length that is decided at runtime instead of compile time. These arrays are beneficial for making numerical algorithm programming more straightforward. C99, a C programming standard, approves the use of variable sized arrays. Below is a C prog...
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...
在C语言中,遇到“variable-sized object may not be initialized”这个错误时,通常意味着你试图用一个变量来定义数组的大小,并在定义的同时进行初始化,但C语言标准并不支持这种操作。下面我将分点详细解释这个问题及其解决方案。 1. 什么是“variable-sized object”? “variable-sized object”指的是在编译时大小未...

The main purpose is to pass structure containing a lot of variables including several variable-sized arrays. The problem is that the following code is working in step-by-step debugging mode, but crashes in release mode. Following e...

Recall that in C, a function that takes a two-dimensional array argument must specify the number of columns in the argument list, so it is quite common for C programmers to only use one-dimensional arrays, and to write explicit code for converting pairs of subscripts into a single dimension...
