Visual Studio 2013 C Syntax outlining

Question

Is there a way in Visual Studio 2013 to outline (in red) undeclared C functions? It seems that by default VS2013 considers that each unknown function is implicit.

Thanks

Answer 1

Microsoft Visual Studio is notoriously bad at the modern C standards, and is pretty much stuck at C89. The 2013 version improved on this a bit, but nothing much.

I believe it indeed still takes undeclared functions to implicitly return int. The IDE just follows the compiler in this regard (which it should...).

What you probably already know is that you can compile some but not all C code as C++, and then most C99 rules like the one you're on about here come into play. Just save your source file as .cpp or equivalent and presto.

That, or use a decent IDE that has support for the language you use.
