Prefix Header
In computer programming, a prefix header is a feature found in some C (programming language), C or C++ compilers used to ensure that a certain snippet of code is inserted at the beginning of every file. Overview In the C (programming language), C and C++ programming languages, a header file is a computer file, file whose text is included in another source file by the compiler, usually by the use of compiler directives at the beginning of the source file. A prefix header differs from a normal header file in that it is ''automatically'' included at the beginning of every source file by the compiler, without the use of any compiler directives. Prefix headers are usually precompiled header, pre-compiled in order to reduce compilation times. Use of prefix headers outside of this purpose can make your code more difficult to maintain & less re-usable. Prefix headers can also be used for cross-platform support. On Unix-like, *NIX systems, it is common to have a config.h header file ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Programming
Computer programming is the process of performing a particular computation (or more generally, accomplishing a specific computing result), usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms (usually in a chosen programming language, commonly referred to as coding). The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task (which can be as complex as an operating system) on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the application domain, specialized algori ...
