The document discusses exception handling in C and C++. It covers exception fundamentals, and techniques for handling exceptions in C such as return values, global variables, goto statements, signals, and termination functions. It also discusses exception handling features introduced in C++ such as try/catch blocks and exception specifications.
An exception is a run-time error. Proper handling of exceptions is an important programming issue. This is because exceptions can and do happen in practice and programs are generally expected to behave gracefully in face of such exceptions. Unless an exception is properly handled, it is likely to result in abnormal program termination and potential loss of work. For example, an undetected division by zero or dereferencing of an invalid pointer will almost certainly terminate the program abruptly.
Exception handling consists of three things: (i) the detecting of a run-time error, (ii) raising an exception in response to the error, and (ii) taking corrective action. The latter is called recovery. Some exceptions can be fully recovered from so that execution can proceed unaffected. For example, an invalid argument value passed to a function may be handled by substituting a reasonable default value for it. Other exceptions can only be partially handled. For example, exhaustion of the heap memory can be handled by abandoning the current operation and returning to a state where other operations (such as saving the currently open files to avoid losing their contents) can be attempted.
C++ provides a language facility for the uniform handling of exceptions. Under this scheme, a section of code whose execution may lead to run-time errors is labeled as a try block. Any fragment of code activated during the execution of a try block can raise an exception using a throw clause. All exceptions are typed (i.e., each exception is denoted by an object of a specific type). A try block is followed by one or more catch clauses. Each catch clause is responsible for the handling of exceptions of a particular type.
When an exception is raised, its type is compared against the catch clauses following it. If a matching clause is found then its handler is executed. Otherwise, the exception is propagated up, to an immediately enclosing try block (if any). The process is repeated until either the exception is handled by a matching catch clause or it is handled by a default handler.

Component Object Model (COM, DCOM, COM+)Peter R. Egli
Overview of Microsoft COM / DCOM technology.
DCOM is Microsoft's component technology and can be roughly compared to CORBA technology. DCOM is however tightly bound to the Windows operating system (Win32 API). Windows Runtime is a newer Microsoft technology that borrows much of the concepts of COM/DCOM.
Java Exception Handling, Assertions and LoggingRiccardo Cardin
This presentation introduces the java exception handling mechanisms. In detail, the main focus of the slides is to show how the language implements its exception handling polices, such as:
- Checked and uncheked exception
- Try / catch blocks
- Assertions
- Logging
The presentation is took from the Java course I run in the bachelor-level informatics curriculum at the University of Padova.
Exceptions are a powerful mechanism for centralized processing of errors and exceptional situations. This mechanism replaces the procedure-oriented method of error handling in which each function returns a code indicating an error or a successful execution.

Kinect is a multimedia sensor from Microsoft. It is shipped as the touch-free console for Xbox 360 video gaming platform. Kinect comprises an RGB Camera, a Depth Sensor (IR Emitter and Camera) and a Microphone Array. It produces a multi-stream video containing RGB, depth, skeleton, and audio streams.
Compared to common depth cameras (laser or Time-of-Flight), the cost of a Kinect is quite low as it uses a novel structured light diffraction and triangulation technology to estimate the depth. In addition, Kinect is equipped with special software to detect human figures and to produce its 20-joints skeletons.
Though Kinect was built for touch-free gaming, its cost effectiveness and human tracking features have proved useful in many indoor applications beyond gaming like robot navigation, surveillance, medical assistance and animation.
The new standard for C++ language has been signed in 2011. This new (extended) language, called C++11, has a number of new semantics (in terms of language constructs) and a number of new standard library support. The major language extensions are discussed in this presentation. The library will be taken up in a later presentation.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Discuss the roles of jmp_buf (including its reuse at multiple points in the code) and int (as an encoded exception object - much like the return value). They provide scalability - Multiple buffers, multiple assignments to buffers and multiple return values. Note that this mechanism merges the advantages of goto and return value and offers more. It offers the basic control for exception handling in C++ (sans the local object cleanup)
Green arrows show the normal flow. Red one shows abnormal flow. Oval areas correspond to try, catch and throw.
Can be asynchronous - interrupt driven. Discuss the semantics for raise() and signal(). Highlight why this can be nearest to exception handling in C++.
