  C programming language - Wikipedia, the free encyclopedia
C was created with one important goal in mind: to make it easier to write large programs with fewer errors in the procedural programming paradigm, but without encumbering the writer of the C compiler by complex language features.
C is often used in low-level systems programming, where it may be necessary to treat an integer as a memory address, a double-precision value as an integer, or one type of pointer as another.
C is used as an intermediate language by some high-level languages (Eiffel, Sather; Esterel) which do not output object or machine code, but output C source code only, to submit to a C compiler, which then outputs finished object or machine code.

 ANSI C - Wikipedia, the free encyclopedia
ANSI C (Standard C) is one standardized version of the C programming language.
For example, two different C compilers may have different feature sets, or may implement certain parts of the language in subtly different ways.
In this case, the American National Standards Institute created a standard for C, and it is referred to as ANSI C. When compilers and programmers stick to one standard such as ANSI C, then portability follows relatively easily.

 comp.lang.c Answers to Frequently Asked Questions (FAQ List)   (Site not responding. Last check: 2007-11-07)
C compilers only allocate memory for objects explicitly mentioned in the source code (in the case of strings, this includes character arrays and string literals).
The array is therefore not a true C string and cannot be used with strcpy, printf %s, etc. Most of the time, you should let the compiler count the initializers when initializing arrays (in the case of the initializer "abc", of course, the computed size will be 4).
ANSI C introduces new features and complexities not found in KandR C. You'll especially need to be careful of prototyped function calls; you'll probably need to insert explicit casts.

There's a hot new programming language and its name is C! The update to the International Standard for the C programming language, which has been under development for the past several years, was ratified in the fall of 1999, and was published and became official in December, 1999.
They take it is a personal insult when they ask a question in a newsgroup which discusses standard C or C++ and receive a response indicating that the language provides no answer, along with a suggestion for a more appropriate newsgroup for them to try.
High level functions provided by C were standardized in the C standard library, which is still a part of C++ to this day, and Unix operating system functions which could be used equally by other languages were removed from the language.

 The C Programmig Language FAQ   (Site not responding. Last check: 2007-11-07)
A: When C requires the Boolean value of an expression (in the if, while, for, and do statements, and with the &&, , !, and ?: operators), a false value is inferred when the expression compares equal to zero, and a true value otherwise.
A: Under ANSI C, the text inside a "turned off" #if, #ifdef, or #ifndef must still consist of "valid preprocessing tokens." This means that there must be no newlines inside quotes, and no unterminated comments or quotes (note particularly that an apostrophe within a contracted word looks like the beginning of a character constant).
