How is it possible to declare nothing inside main() in C++ and yet have a working application after
...int main() {}
In this code, the global variable ignore has to be initialized before entering into main() function. Now in order to initialize the global, print_fibs() needs to be executed where you can do anything — in this case, compute fibonacci numbers and print them! A similar thing I've sho...

Once you know a few basic rules, it's not hard to generalize them. I'll do my best to explain with a few examples. Since you're talking about evaluating these "by hand," I'll suggest some simple substitution rules. Basically, you might find it easier to understand an expression if a...
Why not be dependently typed?

Platform independent size_t Format specifiers in c?
I want to print out a variable of type size_t in C but it appears that size_t is aliased to different variable types on different architectures. For example, on one machine (64-bit) the following code does not throw any warnings:

Dual emission of constructor symbols
...ding to the ABI, the mangled name for your Thing::foo() is easily parsed:

You can read the constructor names similarly, as below. Notice how the constructor "name" isn't given, but i...
