In computer programming, CAR (car) / k ɑːr / ⓘ and CDR (cdr) (/ ˈ k ʌ d ər / ⓘ or / ˈ k ʊ d ər / ⓘ) are primitive operations on cons cells (or "non-atomic S-expressions") introduced in the Lisp programming language. A cons cell is composed of two pointers; the car operation extracts the first pointer, and the cdr operation ...
BISE Peshawar was established in 1961 by the Government of Khyber Pakhtunkhwa.Previously, it was conducting the examination of intermediate and secondary education for the whole Khyber Pakhtunkhwa province but later, new educational boards were established in Khyber Pakhtunkhwa by the government and now its jurisdiction is Peshawar Division.
The expression is evaluated in the current state of the program. The variable is assigned the computed value, replacing the prior value of that variable. Example: Assuming that a is a numeric variable, the assignment a := 2*a means that the content of the variable a is doubled after the execution of the statement. An example segment of C code:
The g++ compiler implements the multiple inheritance of the classes B1 and B2 in class D using two virtual method tables, one for each base class. (There are other ways to implement multiple inheritance, but this is the most common.) This leads to the necessity for "pointer fixups", also called thunks, when casting. Consider the following C++ code:
For example, the Java language does not allow client code that accesses the private data of a class to compile. [12] In the C++ language, private methods are visible, but not accessible in the interface; however, they may be made invisible by explicitly declaring fully abstract classes that represent the interfaces of the class.

The factory method design pattern solves problems such as: How can an object's subclasses redefine its subsequent and distinct implementation? The pattern involves creation of a factory method within the superclass that defers the object's creation to a subclass's factory method.
