PROGRAM DESCRIPTION: In this assignment, you will write sed and gawk commands to accomplish certain requested functionality. Given the many powerful features of sed and gawk, you are provided with a link to a tutorial for sed as well as gawk to assist you in completing this assignment Using sed For help using sed, you may find the tutorial http://www.grymoire.com/Unix/Sed.html or the actual sed manual https://www.gnu.org/software/sed/manual/sed.html useful a) The // character sequence is often known as C++ style or single-line comments, while the /* */character sequence is often known as C-style or multi-line comments. As an example, assume the following myprog.c file that has a mix of both C-style and C++ style comments // This is a test of how this works #include int mainO // declare some variables here int num1-4; float num2 3.5 // print the result printf'The result is %n", num1 num2); // this does it / does it work?/ return 0; Write a one-line sed command that transforms all of the C++ style (i.e., single-line comments) to the C-style (i.e., multi-line comments) so that after running the appropriate sed command, the following would be output to the terminal /* This is a test of how this works */ #include int mainO
