  • Pointers Pointers – Getting the Address of a Value the Address Operator (&) Returns the Memory Address of a Variable
    System Design and Programming II CSCI – 194 Section 01 CRN: 10968 Fall 2017 David L. Sylvester, Sr., Assistant Professor Chapter 9 Pointers Pointers – Getting the Address of a Value The address operator (&) returns the memory address of a variable. Every variable is allocated a section of memory large enough to hold a value of the variable data type. Commonly char one bytes shorts two bytes int, long, float four bytes double eight bytes Each byte of memory has a memory address. A variable’s address is the address of the first byte allocated to that variable. Ex: char letter; short number; float amount; letter number amount 1200 1201 1203 The addresses of the variables above are used as an example. Getting the address of a variable is accomplished by using the (&) operator in front of the variable name. It allows the system to return the address of that variable in hexadecimal. Ex: &amount //returns the variable’s address cout << &amount // displays the variable’s address Note: Do not confuse the address operator with the & symbol used when defining a referenced variable. Pointers – Sample Program // This program uses the & operator to determine a variable's // address and the sizeof operator to determine its size. #include <iostream> using namespace std; int main() { int x = 25; cout << "The address of x is " << &x << endl; cout << "The size of x is " << sizeof(x) << " bytes\n"; cout << "The value of x is "<< x << endl; } Sample output Pointers Variables Pointer variables or pointers, are special variables that hold a memory address. Just as int variables are designed to hold integers, pointers variables are designed to hold memory addresses.

  • Encapsulation and Inheritance in Object-Oriented Programming Languages
    Encapsulation and Inheritance in Object-Oriented Programming Languages Alan Snyder Affiliation: Software Technology Laboratory Hewlett-Packard Laboratories P.O. Box 10490, Palo Alto, CA , 94303-0971 (415) 857-8764 Abstract Object-oriented programming is a practical and useful programming methodology that encourages modular design and software reuse. Most object-oriented programming languages support data Abstraction by preventing an object from being manipulated except via its defined external operations. In most languages, however, the introduction of inheritanceseverely compromises the benefits of this encapsulation. Furthermore, the use of inheritance itself is globally visible in most languages, so that changes to the inheritance hierarchy cannot be made safely. This paper examines the relationship between inheritance and encapsulation and develops requirements for full support of encapsulation with inheritance. Introduction. Object-oriented programming is a practical and useful programming methodology that encourages modular design and software reuse. One of its prime features is support for data Abstraction, the ability to define new types of objects whose behavior is defined Abstractly, without reference to implementation details such as the data structure used to represent the objects. Most object-oriented languages support data Abstraction by preventing an object from being manipulated except via its defined external operations. Encapsulation has many advantages in terms of improving the understandability of programs and facilitating program modification. Unfortunately, in most object-oriented languages, the introduction of inheritance severely compromises encapsulation. This paper examines the issue of encapsulation and its support in object-oriented languages. We begin by reviewing the concepts of encapsulation and data Abstraction, as realized by most object-oriented language.

  • Migration of Threads Containing Pointers in Distributed Memory Systems
    Migration of Threads Containing Pointers in Distributed Memory Systems Saisanthosh Balakrishnan Karthik Pattabiraman Electrical and Computer Engineering Department of Information Technology University of Wisconsin at Madison Sri Venkateswara College of Engineering Madison, WI 53706, USA Sriperumbudur, Madras, India [email protected] karthik [email protected] Abstract Dynamic migration of lightweight threads support both data locality and load balancing. However, migrating threads that contain pointers referencing data in both the stack and heap, among heteroge- neous systems remains an open problem. In this paper we describe the design of a system to migrate threads with pointers referencing both stack and heap data. The system adopts an object-based ap- proach for maintaining consistency because this provides fine-grained sharing with low overhead. Also, it does not rely on the operating system’s virtual memory interface to detect writes to shared data. As a result, threads can be migrated between processors in a heterogeneous distributed memory environ- ment without making any modifications to the operating system and in a totally transparent way to the migrating thread. 1 Introduction Lightweight threads, or user level threads, have become increasingly popular over the last few years due to their shorter context switch time and portable implementation. This is especially so for threads running in a distributed memory environment. Thread migration is the process of moving or migrating a thread from one processor to a remote processor. This provides dynamic load balancing and failure recovery in a multi-threaded environment. One of the most difficult problems while migrating the state of a thread is dealing with pointers in the migrant thread.
