The following C programmain(){ fork() ; fork() ; printf ("yes&qu...
Number of times YES printed is equal to number of process created. Total Number of Processes = 2n where n is number of fork system calls. So here n = 2, 24 = 4
fork (); // Line 1
fork (); // Line 2
fork (); // Line 1
fork (); // Line 2
So, there are total 4 processes (3 new child processes and one original process). Option (C) is correct.

The following C programmain(){ fork() ; fork() ; printf ("yes&qu...
"Hello World\n") ; }
Explanation:
This program uses the fork() function twice, which creates two child processes. The parent process and each child process then execute the printf statement, resulting in the output of "Hello World" four times.
The execution of the program can be visualized as follows:
- The original process (parent) forks, creating a child process (child 1).
- Both the parent and child 1 processes fork again, creating two more child processes (child 2 and child 3).
- Each of the four processes executes the printf statement, resulting in the output of "Hello World" four times.
Therefore, the output of this program will be:
Hello World
Hello World
Hello World
Hello World
Note: The order in which the output is displayed may vary depending on the scheduling algorithm of the operating system.
