This article introduces the relevant knowledge of "whether VC++ supports C99". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

There is no doubt that VC++ supports ANSI C, but I can see two arguments about whether or not to support C99:

1. C99 is not supported.

two。 Individual features of C 99 are supported.

What on earth is the situation? I experimented with VC++ 2010 and determined that VC++ 2010 supports the following features of C99:

Single-line comments at the beginning of / / are supported

Data types such as long long are supported, but the format strings of printf and scanf do not support long long types.

Support for variable parameter macros

VC++ 2010 does not support the following features of C99:

Support for arrays of variable length

The variable declaration does not have to be placed at the beginning of the statement block

In addition to the existing _ _ line__, _ _ file__, add _ _ func__ to get the current function name.
