问题
In Visual Studio 2005, I'm trying to compile a .c file:
int i = 6;
int a[i];
It doesn't work, so which standard does my compiler follow?
回答1:
Visual Studio only supports C89/90. They have no support for C99. Therefore you cannot use variable-length arrays in Visual Studio. Furthermore, Microsoft has no plans to add support for C99 in their C compiler.
