An error result or an unpredictable behavior on your program not caused by the operating system but that occurs in your program is called an exception. The ability to deal with a program’s eventual abnormal behavior is called exception handling. C++ provides three keywords to handle an exception...
you can’t predict when you’ll receive a file I/O error, run out of system memory, or encounter a database error. These things are generally unlikely, but they could still happen and you want to be able to deal with them when they do occur. This is where exception handling comes ...
Exception Handling is there in C++. The Concept of Virtual functions and also Constructors and Destructors for Objects. Inline Functions in C++ instead of Macros in C language. Inline functions make complete function body act like Macro, safely. Variables can be declared anywhere in the program ...
In the above example,nameis initialized with the string"Alex", which contains five characters (four explicit characters and a null-terminator). We then setnameto a larger string, and then a smaller string.std::stringhas no problem handling this! You can even store really long strings in ast...
10. Exception Handling The big difference is that checked exceptions handling is not enforced. To handle general exceptions, we can place the potentially exception-causing code in a try/catch block: try { someActionThatWillThrowAnException() } catch (e) // log the error message, and/or hand...
Figure 1-1 VPN Solutions Center: MPLS Solution in the Service Provider Network As shown in Figure 1-1, a customer edge router (CE) is connected to a provider edge router (PE) in such a way that the customer's traffic is encapsulated and transparently sent to other CEs, thus creating ...
In Java, The PreparedStatement interface is a subinterface of Statement. It is mainly used for the parameterized queries. A question mark (?) is passed for the values. The values to this question marks will be set by the PreparedStatement. Methods of this interface is given below. ...

In this program, the values “Eric” and “Sandra” are used; but you could use other values instead. The SayHelloTo method needs a way of handling the value without knowing what the value actually is. To get round this, C# enables us to create a ‘slot’ for the value, and give ...
Although Objective-C includes syntax for exception handling, Cocoa and Cocoa Touch use exceptions only for programming errors (such as out of bounds array access), which should be fixed before an app is shipped. All other errors—including runtime problems such as running out of disk space or...
