Write a program to compute the perimeter and area of a polygon using an input data file and an output file. a file lab4.c is provided with some of the print statements in it. it is your responsibility to read the power point files: c-3 characters controlstructures. pptx, #20-57 on the various ifs and switchc-4 loops. pptx, #1-24ask any needed questions in classto get the files you need, first move to your csc60 directory: cd csc60the following command will create a directory named lab4 and put all the needed files into it below your csc60 directory. type: cp -r /gaia/home/faculty/bielr/files_csc6 0/lab4 .spaces needed: (1) after the cp ↑ space & dot(2) after the -r(3) after the directory name at the end & before the dot. after the files are in your account and you are still in csc60, you need to type: chmod 755 lab4

(hint: try each out on the system to check your results.) a. find all files on the system that have the word test" as part of their filename. b. search the path variable for the pathname to the awk command. c. find all files in the /usr directory and subdirectories that are larger than 50 kilobytes in size. d. find all files in the /usr directory and subdirectories that are less than 70 kilobytes in size. e. find all files in the / directory and subdirectories that are symbolic links. f. find all files in the /var directory and subdirectories that were accessed less than 60 minutes ago. g. find all files in the /var directory and subdirectories that were accessed less than six days ago. h. find all files in the /home directory and subdirectories that are empty. i. find all files in the /etc directory and subdirectories that are owned by the group bin."
