Maximum number of Zombie processes a system can handle in C++
Given the task is to find the maximum number of Zombie processes that a system can handle or in other words, the program does not stop its execution.
A Zombie process (also known as defunct process) is a process that has completed its process via exit() (system call) but still has an entry in the process table.
Approach used in the below program as follows
Note that <unistd.h>should be added in order to run the program.
In main() function initialize num = 0 of type int which we will iterate until the program stops being executed.
To initiate a zombie process create a while statement with the condition − while( fork() > 0 )
Fork() system call is used for initiating a new process known as the child process which run concurrently and make the fork() call (which is the parent process).
Inside the while loop increment num as well as print it.
Example
#include<iostream>
#include<unistd.h>
using namespace std;
int main(){
int num = 0;
while (fork() > 0){
num++;
cout<<num<<" ";
}
}Output
If we run the above code we will get the following output −
In the above output num stops incrementing at 93. But this number is not fixed and can vary depending upon the system configuration.
