class variables (also called static member variables), where only one copy of the variable is shared with all instances of the class; and instance variables...

class variable is a variable defined in a class of which a single copy exists, regardless of how many instances of the class exist. A class variable is not...

Python by using a publicly exposed instance variable, and later changes the implementation to use a private instance variable exposed through a property descriptor...

For instance, a variable might be referenced by the identifier "total_count" and the variable can contain the number 1956. If the same variable is referenced...

does not require the use of parentheses, it is trivial to change an instance variable into a full function without modifying a single line of calling code...

by all. The two kinds of variables commonly used in Smalltalk are instance variables and temporary variables. Other variables and related terminology depend...

dependent variables, Pressure, and Volume, can quickly be established by changing the value for one or the other, and this is Boyle's law. For instance, if...

Objective-C 2.0 provides non-fragile instance variables by having an extra level of indirection for instance variable access. Another partial solution is...

calculation of the sum of normally distributed random variables is an instance of the arithmetic of random variables. This is not to be confused with the sum of...
