Exit()

This functionexit();Used to terminate the calling function immediately without performing further processing. Asexit();The function call terminates the process. It only calls the constructor of the class. It is declared in the 'stdlib.h' header file of C language. It does not return anything.

The following is the syntax exit();

void exit(int status_value);

Here,

status_value-The value returned to the parent process.

The following is an example exit();

Example

#include <stdio.h>
