Question

Here we will be taking data in as a file. Note that the sample file provided here is not the file that I will use to grade your assignment but the formatting will be the same.

The file you will be imputing to your program is a grade sheet. You will be taking in the grade sheet of 5 students with an unknown amount of grades (the number of possible grades is from 2 to 8). The number of grades will be provided at the top of the file. Your job is to take in the grades average them for each of the 5 students and output the grades in order from greatest to least.

Example input:

Grades 4

Bob 90 89 72 89

Tim 65 60 78 88

Kelly 99 67 75 81

Wesley 44 76 58 67

Anel 100 91 90 96

Example output:

Anel 94.25

Bob 85

Kelly 80.5

Tim 72.75

Wesley 61.25

Final submission should be your .cpp file only

Answer 1

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
