The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
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.
Supports the goto statement. Supports labels with loops and statement blocks. goto is a reserved keyword but is marked as "unused" in the Java specification. Source code can be written to be cross-platform (can be compiled for BSD, GNU/Linux, macOS, Solaris, Windows, etc., without modification) and written to use platform-specific features ...
A static analysis tool used to detect a wide range of defects, identify suspicious code, enforce various coding standards (MISRA/AUTOSAR/etc), calculate and report complex metrics, and implement user-defined checks.

The following is a declaration of the concept "equality_comparable" from the <concepts> header of a C++20 standard library. This concept is satisfied by any type T such that for lvalues a and b of type T, the expressions a==b and a!=b as well as the reverse b==a and b!=a compile, and their results are convertible to a type that satisfies the concept "boolean-testable":
