Same code runs for your provided test4.c but not for our own file that we have created.

[SamSaver]

We have ran our test4.c code on our output file.
It shows perfect output for your file.
But,
It shows syntax error for the same code when we run it from the file that we create (For e.g. test99.c).

Can you please throw some light on this issue and why such stuff is happening?
