3. (14 points=2+4*3) Here is an exercise resembling those from your lab. Answer the following questions about it: #!/bin/sh declare - xbas xxson top top=0 xbas=$1 xson=$2 x=$xbas while [ $x -le $xson ] do top=Stop+$x*$x x=$x+1 done echo "toplam = "Stop a. How did you run this on your computer? b. How many command line arguments do you need and what are they? C. What does the program do? d.

Modify the program so that the checking in part d is incorporated. Write the statements in proper position in the code
