Basically UNIX is Bufferred system.
It has two types of buffering system.
1) Line Buffering
2) Block Buffering.

The printf() in C uses the Linf Buffering System. It means, first the Strings are moved to a Buffer. After the Buffer moves the strings to console/memory. The Buffer is cleared, when any one of the following scenario occurs.
1) If the Buffer is full
2) new line Char "\n" occurs
3) The Buffer is flushed by fflush()
4) The Program Terminates.


from the porter's Solution
we have to use the fflush to clear the buffer.
and also we have to use "\n" in all the printf().

Ex:
printf("Hi\n");
