Should I use char** argv or char* argv[]?
... says: argv is a non-null pointer pointing to at least 5 char*'s
// allows CPU to pre-load some memory.
int main(int c, char *argv[static 5]);
// says: argv is a constant pointer pointing to a char*
int main(int c, char *argv[const]);
// says the same as the previous one

Is it possible to “decompile” a Windows .exe? Or at least view the Assembly?
...roach. Variable names are non-existent; such a thing doesn't exist to your CPU. Library calls are confusing as hell and often require disassembling further binaries. And assembly is hard as hell to read in the best of conditions.
Most professional programmers can't sit and read assembly language wi...
Why doesn't .NET/C# optimize for tail-call recursion?
...what I know.
Sometimes tailcall is a performance win-win. It can save CPU. jmp is
cheaper than call/ret It can save stack. Touching less stack makes for
better locality.
Sometimes tailcall is a performance loss, stack win.
The CLR has a complex mechanism in which to pass more paramet...

Is there a way to access an iteration-counter in Java's for-each loop?
... invoke constructor, scan sooner with GC and finalize. This not only loads CPU but also invalidates the cache all the time. Nothing like this is necessary for local variables. Why do you say that this is "the same"?

When someone writes a new programming language, what do they write it IN?
...ach instruction in the language corresponds to a single instruction to the CPU. Its very low level language and extremely verbose and very labor intensive to write in.
But even writing assembly language requires a program called an assembler to convert the assembly language into "machine language"....
