Suppose I wrote a simple program to take in a filename from a user and then, using that given filename my program would execute a command to copy that file to a particular location (such as my own submission directory). I then made that program executable by someone else. For example, if they gave me a filename "dog.txt", my program would create a string called "cp dog.txt subfolder" and then execute it using the system command. What would I need to do to ensure that nothing malicious was allowed to happen?

The teacher at a school needs help grading an exam with a number of True/False questions. The students’ IDs and test answers are stored in a file. The first entry of the file contains the answer to the test in the form: TTFTFTTTFTFTFFTTFTTF Every other entry in the file is the student’s ID, followed by a blank, followed by the students’ response. For instance, the entry: ABC54102 T FTFTFTTTFTTFTTF TF The student’s ID is ABC54102, answer to question 1 is True, the answer to question 3 is False. Also, the student did not answer question 2 and question 18. The exam has 20 questions. Here is the grading policy: each correct answer is awarded two points, each wrong answer get -1 point, and no answer gets 0 point. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score (total points), followed by the test grade. Assume the following grade scale will be used: 90%-100%, A; 80%-89.99%, B; 70%-79.99%, C; 60%-69.99%,…

Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in Studentlnfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. • Open the tsv file and read the student information. • Compute the average exam score of each student. • Assign a letter grade to each student based on the average exam score in the following scale: o A: 90 =< x o B: 80 =< x < 90 o C: 70 =< x < 80 o D: 60 =< x < 70 o F:x< 60 Compute the average of each exam. • Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt.
