These notes are written based on the book The C Programming Language, by Brian Kernighan and Dennis Ritchie, or K&R (The second edition was published in 1988 by Prentice-Hall, ISBN 0-13-110362-8.). The sections are cross-referenced to those of K&R, for the reader who wants to pursue a more in-depth exposition.

Pointers and Strings the study of strings is useful to further tie in the relationship between pointers and arrays. It also makes it easy to illustrate how some of the standard C string functions can be implemented. Finally it illustrates how and when pointers can and should be passed to functions.

Dr. John P. Abraham, Professor Until now we have talked about variables that hold values of differing data types. For example: int x =20; The memory location referenced by x has a value of 20. float y=21.22; The memory location referenced by y has a value of 21.22. In early chapters we discussed that a variable name is an alias for a memory address. What if we wanted to know the address of the memory location where the inter variable x that has a value of 20 is stored? We can use the address operator &x to do that....

Describe Single Inheritance Describe Base class and Derived class Access Base class members and use pointers in classes Describe types of inheritance Describe Constructors and Destructors under inheritance Describe how to call Member Functions of the Base Class and Derived Class Describe Container Classes To maintain and reuse class objects easily, we need to be able to relate classes of similar nature to another. Single inheritance is the process of creating new classes from an existing base class.

Definition of delegate • Class package some signature methods • Using in event-handling model of C# • Like C/C++ method pointers, but more specific – Type safe – Object- oriented mechanism • Delegates are classes – Can create instances of delegates – Delegates can refer one or more methods

In order to develop Linux device drivers, it is necessary to have an understanding of the following: • C programming. Some in-depth knowledge of C programming is needed, like pointer usage, bit manipulating functions, etc. • Microprocessor programming. It is necessary to know how microcomputers work internally: memory addressing, interrupts, etc. All of these concepts should be familiar to an assembler programmer. There are several different devices in Linux. For simplicity, this brief tutorial will only cover type char devices loaded as modules. ...
