This is a linux activity
Write a simple C or C++ program to call fork() and print a message with its PID (e.g., "This is process PID") where PID is the process ID of the process. You may write one program to do all cases (or a separate program to do each case).
Case1. fork(); // followed by a print statement
Case2. fork(); fork(); // followed by a print statement
Case3. fork(); fork(); fork(); // followed by a print statement
Case4.
if (pid=fork() && pid2 = fork()) {fork();}
if (pid=fork() && pid2 = fork()) {fork();}
if (pid=fork() && pid2 = fork()) {fork();}
// followed by a print statementCase 5.
for (int i=1; i<=5; i++) {fork();}
// followed by a print statement
