2. C (programming language) - Wikipedia

   en.wikipedia.org/wiki/C_(programming_language)

   C (pronounced / ˈsiː / – like the letter c) [6] is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems code (especially in kernels [7 ...

3. C standard library - Wikipedia

   en.wikipedia.org/wiki/C_standard_library

   C standard library. The C standard library or libc is the standard library for the C programming language, as specified in the ISO C standard. [1] Starting from the original ANSI C standard, it was developed at the same time as the C library POSIX specification, which is a superset of it. [2][3] Since ANSI C was adopted by the International ...

4. C syntax - Wikipedia

   en.wikipedia.org/wiki/C_syntax

   A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.

5. C preprocessor - Wikipedia

   en.wikipedia.org/wiki/C_preprocessor

   The C preprocessor is the macro preprocessor for several computer programming languages, such as C, Objective-C, C++, and a variety of Fortran languages. The preprocessor provides inclusion of header files, macro expansions, conditional compilation, and line control. The language of preprocessor directives is only weakly related to the grammar ...

6. The C Programming Language - Wikipedia

   en.wikipedia.org/wiki/The_C_Programming_Language

   The C Programming Language (sometimes termed K&R, after its authors' initials) is a computer programming book written by Brian Kernighan and Dennis Ritchie, the latter of whom originally designed and implemented the C programming language, as well as co-designed the Unix operating system with which development of the language was closely intertwined.

7. C mathematical functions - Wikipedia

   en.wikipedia.org/wiki/C_mathematical_functions

   C mathematical functions. C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. [1][2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions.

8. List of C-family programming languages - Wikipedia

   en.wikipedia.org/wiki/List_of_C-family...

   C-family languages have features like: Code block delimited by curly braces ({}), a.k.a. braces, a.k.a. curly brackets. Semicolon (;) statement terminator. Parameter list delimited by parentheses (()) Infix notation for arithmetical and logical expressions. C-family languages span multiple programming paradigms, conceptual models, and run-time ...

9. C date and time functions - Wikipedia

   en.wikipedia.org/wiki/C_date_and_time_functions

   The C date and time operations are defined in the time.h header file (ctime header in C++). returns the current time of the system as a time_t value, number of seconds, (which is usually time since an epoch, typically the Unix epoch). The value of the epoch is operating system dependent; 1900 and 1970 are often used. See RFC 868.
