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 ...
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 ...
Programmable calculators allow the user to write and store programs in the calculator in order to solve difficult problems or automate an elaborate procedure. Programming capability appears most commonly (although not exclusively) in graphing calculators , as the larger screen allows multiple lines of source code to be viewed simultaneously (i ...
C++11 introduced the keyword constexpr, which allows the user to guarantee that a function or object constructor is a compile-time constant. [11] The above example can be rewritten as follows: constexpr int get_five () { return 5 ;} int some_value [ get_five () + 7 ]; // Create an array of 12 integers.
In many languages, notably the C family, l-values have storage addresses that are programmatically accessible to the running program (e.g., via some address-of operator like "&" in C/C++), meaning that they are variables or de-referenced references to a certain memory location.
In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages , the assignment statement (or expression) is a fundamental construct.

The C++ language has two main components: a direct mapping of hardware features provided primarily by the C subset, and zero-overhead abstractions based on those mappings. Stroustrup describes C++ as "a light-weight abstraction programming language [designed] for building and using efficient and elegant abstractions"; [ 15 ] and "offering both ...
