The function Exit() is commonly used in programming to terminate a program or script. When called, it stops all processes and closes the application immediately. This function is essential for managing program flow and ensuring that resources are released properly. In many programming languages, such as Python and Java, Exit() can take an optional status code as an argument. This code indicates whether the program ended successfully or encountered an error. A status code of zero typically signifies a successful exit, while any non-zero value indicates an error or abnormal termination.
