Process Scheduling

Question

printf("Hello");

if(!fork())

printf("World");

Comments

printf enclosed in if statement therefore it print only one time

but now question is " is it print by parent process or child process? "

fork() ---> return 0 for child process and non-zero for parent process

therefore we can conclude that it will print by child process

---

first statement prints : 

hello.

for second statement one more child process will be created..

for parent value of fork = +v3 number say (23)

for chiild value of fork = 0

for if(!fork()) -----> only child process will execute... after second statement. printing world.

and for parent process it comes out after second statement as (!23 =0)

so answer will be HELLO WORLD
