Error handling is a programming practice that involves anticipating and managing errors that may occur during the execution of a program. It ensures that the program can respond gracefully to unexpected situations, such as invalid user input or system failures, rather than crashing. By implementing error handling, developers can provide informative messages to users and maintain the program's stability.
Common techniques for error handling include using try-catch blocks, which allow developers to attempt a block of code and catch any exceptions that arise. Other methods include validating input data and logging errors for further analysis. Effective error handling improves user experience and software reliability.
