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.
In the C programming language, an escape sequence is specially delimited text in a character or string literal that represents one or more other characters to the compiler.It allows a programmer to specify characters that are otherwise difficult or impossible to specify in a literal.
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 ...

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 Amsterdam Compiler Kit (ACK) is a retargetable compiler suite and toolchain written by Andrew Tanenbaum and Ceriel Jacobs, since 2005 maintained by David Given. [1] It has frontends for the following programming languages : C , Pascal , Modula-2 , Occam , and BASIC .
To avoid this gotcha, some programming languages such include specific syntax for when this is desired behavior, such as Python's "walrus" operator (:=). In languages where this specific syntax does not exist, there is a recommendation [2] to keep the constants in the left side of the comparison, e.g. 42 == x rather than x == 42.
Part of the C standard since C11, [17] in <uchar.h>, a type capable of holding 32 bits even if wchar_t is another size. If the macro __STDC_UTF_32__ is defined as 1, the type is used for UTF-32 on that system. This is always the case in C23. [15] C++ does not define such a macro, but the type is always used for UTF-32 in that language. [16 ...
