C++ Exit Function Explained

The exit function is a function in the C++ standard library that terminates the program immediately and returns a specified exit code. It performs some cleanup tasks, such as closing files and flushing buffers, before terminating the program.

The exit function has one parameter, which is the exit code. The exit code is an integer used to indicate the program’s exit status. Typically, 0 signifies a normal program exit, while a non-zero value indicates an abnormal or error exit.

Using the exit function allows you to terminate the program’s execution at any point without waiting for a return. However, it is important to note that the exit function instantly ends the program, potentially resulting in some resources not being released or cleanup work not being completed, so it should be used cautiously.
