Could you explain what is meant by exceptions in programming?

Exceptions in programming are mechanisms for handling errors and unusual situations that occur during program execution. When an error occurs (for example, division by zero, file access error, invalid input), the program can "throw" an exception — a special object that signals a problem.

Exception handling allows:

• Catching the error in a special try-catch block.
• Responding to the error, for example, by displaying a message, executing alternative code, or terminating the program gracefully.

Example in C#:

try {
    int x = 10 / 0; // will throw DivideByZeroException
} catch (DivideByZeroException ex) {
    Console.WriteLine("Error: division by zero.");
}

Thus, exceptions help make the program more robust and manageable when errors occur.
