Question

fork();

fork();

printf("Gate2024");

fork();

what will be the answer?

Comments

i know on first look it looks like 4. I am getting 8. my logic is printf is buffered output so it waits till execution of last fork and then for the 8 processes(1parent and 7 child) it flushes the "Gate2024". Please correct me if my logic is incorrect. thanks

It prints, 4-times "Gate 2024" with 8 child processes created

only 4 times print the message and 8 times process is created (one parent+seven child)

yes every one is correct in the comment here 4 times  printed because when first time fork is called  the one child and one parent created and second time called then child is created  two process and parent also created two process so total 4 process is created so after this every four process call the printf statement and   and print four time Gate2024  and last fork created total 8 process so only 4 time Gate 2024 is printed

Answer 1

Here, first two fork()'s will be executed and "Gate2024" will be printed 4 times with one parent process and 3 child proceses , last fork() executes and 8 processes(1 parent , 7 child)  will be created.
