Create 4 arrays: a 1-D array to store the students id, 1-D array to store the students names, a parallel 2-D array to store the test scores, and a parallel 1-D array to store letter grades. Read data into the 3 arrays from the file data121.txt. If the file is not found, the program needs to terminate with this error, Data file not found. Calculate and store a letter grade into a 1-D array based on the total score, sum up all scores for each student, for example if the total score is 82, then the grade is a B. Score Letter grade 90 ~ 100 A 80 ~ 89 B 70 ~ 79 C 60 ~ 70 D 0 ~ 60 F Once the data has been read into the arrays, implement the following 3 steps. Display all students names, scores, and their grades, Calculate and display a student name that received overall maximum points, Calculate and display the average of all elements in the array test scores, Generate a new text file report121.txt and save students names and grades. Use c++ language.

Also if no functions could be used, that would be great.

This is the text file contents.
