C++ assignment

Immediate Help needed. Write a C++ program that asks user for an exam score and then convert it to a letter grade. For example: 95 is an A and 56 is a D. The following scale is used for the convertion If a score is greater than or equal to 90, it is an A If a score is less than 90 and is greater than or equal to 80, it is a B If a score is less than 80 and is greater than or equal to 70, it is a C If a score is less than 70 and is greater than or equal to 60, it is a D If score is less than 60, it is an F. I am using this for a class (for teaching some examples of basic programming) -- so I need the following: 1)You need to first design an algorithm for this problem. Draw a flow chart for converting numerical grades to letter grades using the scale given above (multiple decision making symbols should be used in the flow chart). 2)Write the C++ program to implement your flow chart 3) Test your program using the following data: 100, 90, 89, 80, 79, 70, 69, 60, 59, and 56 and a few more of your choice. 4.) Use 'cin' and 'cout' when writing the application ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
