50. Getting Started with C++: Exception Handeling
Exception handling is a powerful feature in C++ that allows programmers to gracefully handle errors that may occur during program execution. When an error occurs, an exception is thrown, and the program can then catch the exception and handle it appropriately, rather than crashing or terminating unexpectedly.
In C++, there are several types of exceptions, such as runtime errors, logic errors, and input/output errors, and each type requires a different approach to handle it. The basic idea behind exception handling is to use try-catch blocks, where the code that is likely to throw an exception is placed in a try block, and the code that handles the exception is placed in a catch block.
When an exception is thrown in the try block, the program will exit the try block and jump to the appropriate catch block that matches the type of the exception. If there is no matching catch block, the program will terminate.
C++ also provides a mechanism for creating custom exceptions, which can be useful for handling errors specific to a program or library. Custom exceptions are typically derived from the standard exception class and can include additional data members and methods.
Overall, exception handling is an essential tool for writing robust and error-free C++ code, as it allows programmers to anticipate and handle potential errors and ensure that their programs continue to run smoothly even in unexpected circumstances.
