Question

A continuation of your grading software will be made you do not need your other code for this assignment). In this one you will intake a students first name and last name from a file called "students.txt". Next, there is a file called grades.txt that contains the grades in a course. There will be three grades for each student in "grades.txt" (see example file bellow). In "student.txt" there are two students first and last names. In "grades.txt" the grades for each student will be on the same line number as the students name was on in "students.txt". So if line 1 of "students.txt" contains: Joe Blow then line 1 of "grades.txt" would contain Joe Blow's grades: 85 54.356 Into an output file called "report.txt" output the student's last name then a comma the their first name. Following this, calculate their average and assign a letter grade using the following scale: Al: grade >= 90 'B': 90 > grade >- 80 C': 80 > grade >- 70 'D': 70 > grade >= 60 'F: grade < 60 If the final grade of a student is greater than 100 instead of printing their letter grade output the statement Teacher was far too easy". The report.txt" should have a heading on each of the columns the first saying "Student's Name" and the second saying "Student's Grade" Sample input files: students.txt Brades.txt Sample output file:

char getGrade(float grade)
{
   if(grade >= 90)

{
   return 'B';
}

   {
   outfile <<lastName[index]<<", "<<firstName[index]<<" Teacher was far too easy"<<endl;
