Question
I want it to be done in C++. And my file should be formatted in file.cpp (not in file.c). The file should be prog02_myname.cpp. I can put my name later. Thank you so much.

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 Zelle er 452313 78 86 91 64 90 7 274253 BB 77 91 66 82 93 Carl Wilson. 112235 87 99 93 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 'In' 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 cutofffor 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.da a table showing each student's name (Last, First), identification number, course average (rounded to 1 decimal place) 35% Tue Feb 7 12:38 AM a E nhat Other Bookmarks 7Loader ISO.
