1. Write a sed script which transforms a text file into proper C

Input File

The first three lines should be ignored Don't include them in your output So you'll need to tell 'sed' to ignore them

# # This is a comment #

BEGIN HELLO # so is this! END

Copy and paste that into a file on your machine, and write a sed script to turn it into the following:

#include

int main()

{

printf("hello, world ");

}

You will need to:

• Delete the first three lines of the input
• Delete anything after #, leaving no empty lines behind
• Convert BEGIN into the #include and main lines
• Convert HELLO into the printf
• Convert END into the trailing }

Your script should work on similar input files.
