Operations on data structures

OPERATIONS ON DATA STRUCTURES
This section discusses the different operations that can be execute on the different data structures before mentioned.
Traversing It means to process each data item exactly once so that it can be processed. For example, to print the names of all the employees in a office.
Searching It is used to detect the location of one or more data items that satisfy the given constraint. Such a data item may or may not be present in the given group of data items. For example, to find the names of all the students who secured 100 marks in mathematics.
Inserting It is used to add new data items to the given list of data items. For example, to add the details of a new student who has lately joined the course.
Deleting It means to delete a particular data item from the given collection of data items. For example, to delete the name of a employee who has left the office.
Sorting Data items can be ordered in some order like ascending order or descending order depending on the type of application. For example, arranging the names of students in a class in an alphabetical order, or calculating the top three winners by arranging the participants’ scores in descending order and then extracting the top three.
Merging Lists of two sorted data items can be joined to form a single list of sorted data items.
Many a time, two or more operations are applied at the same time in a given situation. For example, if we want to delete the details of a student whose name is X, then we first have to search the list of students to find whether the record of X exists or not and if it exists then at which location, so that the details can be deleted from that particular location.

Introduction to C Programs

INTRODUCTION The programming language ‘C’ was developed by Dennis Ritchie in the early 1970s at Bell Laboratories. Although C was first developed for writing system software, today it has become such a famous language that a various of software programs are written using this language. The main advantage of using C for programming is that it can be easily used on different types of computers. Many other programming languages such as C++ and Java are also based on C which means that you will be able to learn them easily in the future. Today, C is mostly used with the UNIX operating system. Structure of a C program A C program contains one or more functions, where a function is defined as a group of statements that perform a well-defined task.The program defines the structure of a C program. The statements in a function are written in a logical series to perform a particular task. The most important function is the main() function and is a part of every C program. Rather, the execution o...

Performance

Performance ( Optional ) * The I/O system is a main factor in overall system performance, and can place heavy loads on other main components of the system ( interrupt handling, process switching, bus contention, memory access and CPU load for device drivers just to name a few. ) * Interrupt handling can be relatively costly ( slow ), which causes programmed I/O to be faster than interrupt driven I/O when the time spent busy waiting is not excessive. * Network traffic can also loads a heavy load on the system. Consider for example the sequence of events that occur when a single character is typed in a telnet session, as shown in figure( And the fact that a similar group of events must happen in reverse to echo back the character that was typed. ) Sun uses in-kernel threads for the telnet daemon, improving the supportable number of simultaneous telnet sessions from the hundreds to the thousands.   fig: Intercomputer communications. * Rather systems use front-end processor...

HEAT AND THERMODYNAMICS

Heat: * Temperature is the thermal state of the body, that chooses the direction of flow of heat.  * “Heat is a form of energy transfer between two systems or a system and its surroundings due to temperature difference between them.  Specific heat capacity  * Specific heat capacity of a substance is determined as the quantity of heat required to raise the temperature of 1 kg of the substance through 1K. Its unit is J kg^–1K^–1. * The specific heat capacity of water is the highest for any substance, 4180 J/kg K. It is 30 times the specific heat capacity  of mercury which is about 140J/kg K.  Specific Latent Heat  Specific Latent Heat of fusion of any substance is the quantity of heat energy needed to melt one kilogram of a substance without change in temperature. The symbol used is L. The unit for specific  latent heat is Joule/kilogram or J/kg  The Gas Laws  * Boyle’s Law  “Temperature remaining constant, the pressure of a given mass of ...
