operatorsCB

operatorsCB refers to a set of programming constructs, often found in object-oriented languages, that allow for the definition of custom behavior for standard operators when applied to user-defined types. These are sometimes called operator overloading. The "CB" likely signifies "callback" or "custom behavior," indicating that the operator's action is being defined by the programmer rather than relying on a default, built-in implementation.

When a programmer defines operatorsCB, they are essentially creating new meanings for symbols like +, -, *, /, ==, !=, <, >, <=, and >= when used with their own classes or structures. For instance, a programmer might define the addition operator (+) to concatenate two strings, or to add two complex numbers element-wise, rather than just performing arithmetic on primitive types. This allows for more intuitive and expressive code, making it appear as though the custom types are behaving like built-in ones.

The implementation of operatorsCB typically involves defining special member functions or standalone functions that are invoked when the corresponding operator is encountered in the code with operands of the specified custom type. The syntax and availability of operatorsCB vary significantly between programming languages. Some languages offer extensive support, allowing for a wide range of operators to be redefined, while others have more limited capabilities or do not support it at all. Careful use of operatorsCB is important to maintain code readability and avoid unexpected behavior.
