These features are used to do some startup task before executing the main, and some cleanup task after executing main. To do this task we have to put attribute for these two functions. When the attribute is constructor attribute, then it will be executed before main(), and when the attribute is destructor type, then it will be executed after main(). Syntax void ...

In this section we will see how to execute zombie process and orphan process in a single program in C. Before going to the main discussion, let us see what are the zombie process and orphan process. Zombie Processes A zombie process is a process whose execution is completed but it still has an entry in the process table. Zombie processes usually occur for child processes, as the parent process still needs to read its child's exit status. Once this is done using the wait system call, the zombie process is eliminated from the process table. This is ...
