C-like languages feature two versions (pre- and post-) of each operator with slightly different semantics. In languages syntactically derived from B (including C and its various derivatives), the increment operator is written as ++ and the decrement operator is written as --. Several other languages use inc(x) and dec(x) functions.
This is a list of operators in the C and C++ programming languages.. All listed operators are in C++ and lacking indication otherwise, in C as well. Some tables include a "In C" column that indicates whether an operator is also in C. Note that C does not support operator overloading.

Post increment The stepping of an address past data used, similar to *p++ in the C programming language, used for stack pop operations. Pre decrement The decrementing of an address prior to use, similar to *--p in the C programming language, used for stack push operations.
After the increment, if the pre-increment value was negative (meaning there are processes waiting for a resource), it transfers a blocked process from the semaphore's waiting queue to the ready queue. Many operating systems provide efficient semaphore primitives that unblock a waiting process when the semaphore is incremented.
At the end of an initializer; for example, after the evaluation of 5 in the declaration int a = 5;. Between each declarator in each declarator sequence; for example, between the two evaluations of a ++ in int x = a ++, y = a ++. [8] (This is not an example of the comma operator.) After each conversion associated with an input/output format ...

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.
