I have a list of students and their grades that I want to sort based on grades
After user inputs name and grades of students, I want to be able to sort and output them with the students with highest grades first. I'm not sure how to go about this using a list and grades ranging from F-A+

is this for homework of some kind?
do you have any restrictions on what you're allowed to use?
in any case, i think implementing a simple bubble sort would be some good programming exercise
a bubble sort works by iterating the input collection multiple times, comparing the current element to the next element, and then swapping them if the first is larger than the second. you repeat this entire process until no more swaps occur
Its a small homework before our last assignment in web development, it says to use a sorting algorithm like bubble or selection sort, so il try and implement bubble sort, iv used it before but not sure how to go about it here. making sure all A+ comes first and F last and everything in between.
You'll need some algorithm to compare the grades, since you're currently storing them as strings
I see, iv only used bubble sort on unsorted arrays, not sure how to do it with a list, im very new at this mind you
I managed to do it with numbers as grades, but I dont know how to do the algorithm to compare strings, as in F-A grades. https://hatebin.com/qjtkqhzcmw
you can probably just create a function to map the letter grades to a number and use that
you can use linq query
List<string> sortedList = students
.OrderBy(i => i.Grade == "A+")
.ThenBy(i => i.Grade == "A")
.ThenBy(i => i.Grade == "B")
.ToList();
It's an assignment, they almost certainly cannot use linq
