There are two kinds of functions: those supplied to you and those you will be writing. The functions that are supplied to you are usually in three categories: those built-in Microsoft Windows operating system, those written in C++ (they are part of the C++ language), and those written by ...
Not in the first edition of "The C programming Language". In the C language of that era, functions that return a value of type int are not declared. However, in the second edition (1988) of the book, the program was changed to: #include <stdio.h...

The aim of this introductory section is to give a brief glimpse of C so that one can quickly write simple programs. C is a function-based language. The basics of writing programs in C have been discussed in this chapter. In C, parameters are passed to functions as arguments. A function...
This is the second enhancement that C++ AMP makes to the C++ language (the other being restrict, which I covered in my previous article). You can only use this new storage class in restrict(amp) functions, and only if the parallel_for_each is tiled, and only for variables declared ...

An Introduction to Delegates Jeffrey Richter Callback functions are certainly one of the most useful programming mechanisms ever created. The C runtime's qsort function takes a callback function to sort elements within an array. In Windows, callback functions are required for window procedures, hoo...

This is a key new language feature of the C++ AMP specification that’s added to the Visual C++ compiler. Functions (including lambdas) can be annotated with restrict(cpu), which is the implicit default, or restrict(amp) as shown in the previous code sample, or with a combination—for ...
