Write a program that reads a list of exam grades entered as Int's in the range of 0 to 100. The program must report the total number of grades and the number of grades in each letter-grade category, where the letter-grade categories are as follows: A 93 <= grade < 100 A- 90 grade <93 B+ 87 <= grade <90 B 83 <= grade <87 B- 80 < grade <83 77 <= grade <80 73 < grade <77 C C- 70 < grade <73 D 60 <= grade <70 F 0<= grade <60 The program must use a negative number as a sentinel value to indicate the end of the input. By definition the negative sentinel value is used only to end the loop. Do not use it in the calculations. The program will prompt the user to enter each grade individually by printing: Enter a grade: C+ ن I If the inputs are: 98 95 87 86 83 92 85 78 74 72 81 71 69 63 50 43-1 The output would be: Total number of grades = 16 Number of A's = 2 Number of A-'s=1 Number of B+'s=1 Number of B's = 3 Number of B-'s=1 Number of C+'s=1 Number of C's = 1 Number of C-'s=2 Number of D's = 2 Number of F's = 2

Where does the term "deppresion" fit in?

How do I learn coding? I want to learn c++ but I don't know what to write. Like I know there is something called a while loop but what is it and what does it do? Do you know any books or websites which can help?
