Explore exception handling and error management from "summary" of C/C++ Programmer's Reference by Herbert Schildt
Exception handling and error management are crucial aspects of programming that allow developers to handle unexpected situations and errors gracefully. In C/C++, exceptions are used to handle errors that occur during program execution, allowing the program to take appropriate action instead of crashing. When an error occurs, an exception is thrown, which can be caught and handled by the programmer. This allows for the separation of error-handling code from the main program logic, making the code more robust and maintainable. By using exception handling, developers can write cleaner and more readable code that is easier to debug and maintain. In C/C++, exceptions are typically handled using try-catch blocks. The try block contains the code that may throw an exception, while the catch block is used to handle the exception if it occurs. By catching exceptions at the appropriate level of the program, developers can control how errors are handled and prevent them from propagating up the call stack. In addition to handling exceptions, C/C++ also provides mechanisms for error management, such as error codes and errno. Error codes are used to indicate the type of error that occurred, allowing the program to take appropriate action based on the error. The errno variable is a global variable that stores the last error code, which can be checked by the program to determine the cause of the error.- Exception handling and error management are essential tools for writing reliable and robust C/C++ programs. By understanding how to handle exceptions and manage errors effectively, developers can create code that is more resilient to unexpected situations and errors, leading to a better user experience and improved software quality.
