It determines whether two values are equal, according to the lefthand operand’s definition of “equal.” The != operator is simply the inverse of ==: it calls == and then returns the opposite. You can redefine != in Ruby 1.9 but not in Ruby 1.8. See Object Equality for a more ...
Operator Overloading in Python Operator Overloading lets you extend the meaning of operators that are predefined. It provides an expanded definition of the operator. The same operator also behaves in different ways with different data types. Take the example of the + operator. It performs additio...
We show that many different overriding operators present in programming languages can be expressed, adopting a mixin-based framework, in terms of three basic operators. In particular we propose two orthogonal classifications: strong (the overridden definition is canceled) or weak (the overridden ...
Bitwise operatorsenable you to manipulate the individual raw data bits within a data structure. They’re often used in low-level programming, such as graphics programming and device driver creation. Bitwise operators can also be useful when you work with raw data from external sources, such as e...
An Operator Statement appears in a module definition.You can define an operator as part of a class or a structure that you are defining. The operator must take that class or structure as at least one of its operands.An operator must use an instance of a programming element as one of its...

This operator is placed after the array variable’s name, as in grades[0] (access the first element in the array assigned to grades; the first element is stored at index 0). Here’s a formal definition:Given variable[index], where index must be of integer (int) type, read a value ...
and consists of any data stored in an unstructured format at an atomic level. In other words, in the unstructured content, there is no conceptual definition and no data type definition—in textual documents, a word is simply a word. Current technologies used for content searches on unstructured...
