***All interaction with the arrays must be done via a pointer.***

***Use pointer arithmetic to traverse the arrays***

Create a program to grade a 20 question true/false test.

All input will come from a file

The first line of the file contains the answer key for the test

For example: TFFTFFTTTTFFTFTFTFTT

Every other entry in the file is the student ID, followed by a space, followed by the students responses.

Spaces in the student's answers indicate the student did not answer a question.

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.

The class has an unknown number of students.

Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points.

The output should be

the students ID,

the student's test score,

the student's letter grade.

Assume the following grade scale:

90%100%, A;

80% 89.99%, B;

70%79.99%, C;

60%69.99%, D;

< 59.99%, F.

All output should be written to a file and formatted properly.

Test scores should be rounded to two decimal places

Use a tab delimiter between student items (listed above)

Write each student's data on a separate line.
