Final answer:
A try scope encapsulates code that may throw an exception and transfers control to a catch clause for error handling, preventing the program from crashing.
Step-by-step explanation:
When programming, a try scope is used to handle errors by encapsulating code that may throw an exception. Within the try block, normal program execution takes place until an error (also known as an exception) occurs. If an error arises, the control is transferred to a corresponding catch clause, if one is present, where the error can be handled accordingly. This prevents the program from crashing and allows the programmer to provide feedback to the user or take corrective action. If no error occurs within the try block, the execution moves to the code following the entire try-catch construct.
