Dennis MacAlistair Ritchie (September 9, 1941 – c. October 12, 2011) was an American computer scientist. [3] He created the C programming language and the Unix operating system and B language with long-time colleague Ken Thompson . [ 3 ]
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.
The cover of the book The C Programming Language, first edition, by Brian Kernighan and Dennis Ritchie. In 1978 Brian Kernighan and Dennis Ritchie published the first edition of The C Programming Language. [18] Known as K&R from the initials of its authors, the book served for many years as an informal specification of the language.

Note that C99 and C++ do not implement complex numbers in a code-compatible way – the latter instead provides the class std:: complex. All operations on complex numbers are defined in the <complex.h> header. As with the real-valued functions, an f or l suffix denotes the float complex or long double complex variant of the function.
Martin Richards (born 21 July 1940) is a British computer scientist known for his development of the BCPL programming language [3] which is both part of early research into portable software, and the ancestor of the B programming language invented by Ken Thompson in early versions of Unix and which Dennis Ritchie in turn used as the basis of his widely used C programming language.

The C date and time functions are a group of functions in the standard library of the C programming language implementing date and time manipulation operations. [1] They provide support for time acquisition, conversion between date formats, and formatted output to strings.
