Question

C++

please make it sifferent and unique

Description Write a program that will read data from the file "p6.dat". The file (that you will create) always contains 15 test scores (whole numbers between O and 100). The test scores are scores for 5 students taking 3 tests, and are arranged, in the file, by the student - that is the first 3 numbers are the test scores for test 1, 2, and 3 for the first student, etc. The program will print: - average per student (5 averages), on a single line, with 2 decimals - average per test (3 averages), on a single line, with 2 decimals - overall best score on a single line - how many scores were Fs (out of the 15, how many were at most 59) on a single line To simplify the code, no validations are needed. That is, assume the file is successfully opened, and that all data are 0-100, and that there are exactly 15 numbers in the file. Note that the program reads the filename
