Grading Tests using Dynamic Arrays

Instructions

Redo Programming Exercise 6 of Chapter 8using dynamic arrays. The instructions have been posted for your convenience.

The history teacher at your school needs help in grading a True/False test. The students IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form:

TFFTFFTTTTFFTFTFTFTT

Every other entry in the file is the student ID, followed by a blank, followed by the students responses. For example, the entry:

ABC54301 TFTFTFTT TFTFTFFTTFT

indicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9 (note the empty space). The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the students ID, followed by the answers, followed by the test score, followed by the test grade.

An example of the program is shown below:

Processing Data Key: TTFTFTTTFTFTFFTTFTTF ABC54102 T FTFTFTTTFTTFTTF TF 27 D

Remember, a space indicates that a question has been skipped. If spaces are added for formating, there are too many or too few, it may affect the accuracy of your program.

Assume the following grade scale: 90%100%, A; 80%89.99%, B; 70%79.99%, C; 60%69.99%, D; and 0%59.99%, F.

\[ \begin{array}{l|lll} \vdots: & 1 & \text { TTFTFTTTFTFTFFTTFTTF } \\ & 2 & \text { ABC54102 } & \text { T FTFTFTTTFTTFTTF TF } \\ & 3 & \text { DEF56278 } & \text { TTFTFTTTFTFTFFTTFTTF } \\ \text { Lill } & 4 & \text { ABC42366 } & \text { TTFTFTTTFTFTFFTTF } \\ & \multicolumn{1}{l}{5} & \text { ABC42586 } & \text { TTTTFTTT TFTFFFTF } \\ \langle> & 6 & & \end{array} \] (3) (0) 1 out of 1 checks passed.
