Undefined behavior — behavior, upon use of a nonportable or erroneous program construct, of erroneous data, or of indeterminately-valued objects, for which the Standard imposes no requirements. “Undefined behavior” means the compiler can do what it wants, so the behavior noticed by Xi Wang can in no way be held against a C90 compiler.
Create a new compiler warning. My guess is that it wouldn't be that difficult to add: add a warning for using sizeof() on a value whose type is the result of array-pointer decay. If you really want the size of the pointer, then you can change the function parameter's type to the pointer type, or use a cast.

But such an argument would be falling into one of the traps that I identified in my blog post about seven common forms of mistake that are made in predicting the future of Artificial Intelligence. In this case it is the mistake of attributing magic to a sufficiently advanced technology.
Linux Internet Server Security and Configuration Tutorial. Security configuration and set-up for Linux servers exposed to the internet: Any computer connected to the internet will require steps and precautions to be taken to reduce the exposure to hacker threats.
The Erlang RunTime System (ERTS) is a complex system with many interdependent components. It is written in a very portable way so that it can run on anything from a gum-stick computer to the largest multicore system with terabytes of memory.
That blinding level of simplicity gets the non-programmer started in under an hour. To run Heroku (on a Mac), you need to download (1.8GB) and install XCode (or another version of GCC for Mac, but the moment you say GCC, the beginner's eyes glaze over). Once you install XCode, you need to open up terminal (no GUI). Then you install homebrew in.
Introduction. Debugging is the cornerstone of programming art. While the meaning of the verb to debug is to remove errors, in reality it is more about seeing step by step execution of a program. As well as examining it against some specification of how program should behave.
Footnotes. The three and a half decades between 1969 and 2003 is a long time. Going by the historical trend curve in number of Unix sites during that period, probably somewhere upwards of fifty million man-years have been plowed into Unix development worldwide.
The Security of Various Programming Languages. Interesting research on the security of code written in different programming languages. We don't know whether the security is a result of inherent properties of the language, or the relative skill of the typical programmers of that language.
This book describes a set of guidelines for writing secure programs. For purposes of this book, a “secure program” is a program that sits on a security boundary, taking input from a source that does not have the same access rights as the program. Such programs include application programs used as viewers of remote data, web applications (including CGI scripts), network servers, and setuid.
Note: What a pointer points to can be on the stack or heap. Ditto a reference. My claim in this statement is not that a pointer must point to the stack. A pointer is just a variable that holds a memory address. This variable is on the stack. Since a reference has its own space on the stack, and since the address is the same as the variable it.
In the past, the need for scripting languages for Java applications has been neglected by many companies, most notably by Sun itself. Although Sun started a JCP process-Java specification request 223 (JSR-223)-in the summer of 2003 to define and create a standard Java interface to scripting languages, it still will be some time until it will be.
