It seems to me that the 10 from the printf output is just a garbage value since the variable o was defined but never initialized.

[@riyazshaik864]

10 isn't a garbage, we gave a limit to write function , you could see at 6:40 part that inside write function we gave buffer value as 10 , so it can store maximum 10 characters, so the buffer was full, it can only written 10 since it's the max buffer we assigned, you change to greater than 14 , you will get different value other than 10 and missing part of the characters will also be printed
