The following code compiles fine on Linux using gcc -std=c99 but gets the following errors on the Visual Studio 2010 C compiler:
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.40219.01 for 80x86 Copyright (C) Microsoft Corporation. All rights reserved. fib.c fib.c(42) : error C2057: expected constant expression fib.c(42) : error C2466: cannot allocate an array of constant size 0 fib.c(42) : error C2133: 'num' : unknown size
The user inputs the amount of Fibonacci numbers to generate. I'm curious as to why the Microsoft compiler doesn't like this code.
