Answer 1

Important Note:
Fork():
No argument
Return processes Id of the Child process.
After the creation of the process, both parent and child process starts execution from the next instruction.

int main()
{
fork();
fork();
fork();
return 0;
}
Output:warning: implicit declaration of function 'fork' [-Wimplicit-function-declaration] fork();
because no execution is involed in the computation.

int main()
{
fork();
fork();
fork();
printf("Chegg is awesome");
return 0;
}

Output:
Chegg is awesome
Chegg is awesome
Chegg is awesome
Chegg is awesome
Chegg is awesome
Chegg is awesome
Chegg is awesome
Chegg is awesome

Number of a process created is always equal to $2^n$
Number of Child process created is always $2^n$-1

Note: I didn't find any link to above 3 pages of code to the last one. So, answering the code of the last page(Fig 3.11).
