Web HTTP server c program help small error

This is what i am getting. I only want it to display the 404 File not found. I dont want all the text below that.

To compile: gcc file.c

./a.out (any port)

To get the 404 page

host/port/

Please also add a printf saying that its listening in the given port. But the may problem is shown in the image. I only want the 404 file not found and not I dont want any text below it.
