C++

Input: An instructor has a class of no more than 40 students each of whom takes 6 tests. For each student in the class, there is one line in the input file. The line contains the student's first name (no more than 10 characters), last name (no more than 12 characters), ID# (a string of 6 characters) and 6 integer test scores. Input text file should be named student_input.dat

Example of file input:

Adam Zeller 452313 78 86 91 64 90 76

Barbara Young 274253 88 77 91 66 82 93

Carl Wilson 112235 87 99 76 93 95 94

Note that a different file will be used for testing. Also note that amount of blank spaces between names, ID, and grades can be arbitrary, i.e., any number. There will be at least one space though. There might be a space between the last grade and the invisible symbol that signifies the end of the line . Total amount of characters for each line will not exceed 256, including the end of the line symbol.

Processing: The program is to read the input file and calculate each student's average and letter grade for the course. The average is calculated by dropping the student's lowest test score and then averaging the remaining 5 scores. In addition, the number of students receiving each letter grade (A, B, C, D, or F) for the course is to be calculated. The cutoff for the letter grades is 89.5 for an A, 79.5 for a B, 69.5 for a C, 59.5 for a D.

Output: The program is to print to an output file (student_results.dat) a table showing each student's name (Last, First), identification number, course average (rounded to 1 decimal place), and letter grade. Following the last student, a summary of the number of students receiving each letter grade is to be printed. All output should be clearly labeled and easy to read. The output file should have a meaningful heading at the top of the file.

Example of file output:

Last_name First_name ID Average_Score Grade

Zeller Adam 452313 82.3 B

Young Barbara 274253 86.2 B

Wilson Carl 112235 93.6 A

Grade Totals:

A 1

B - 2
