- Grade Book A teacher would like to assign a letter grade to a student, based on student's test score. Write a program to help this teacher managing her students' test score. Use the following grading scale to assign a letter grade to a student. Test Score Letter Grade 80 - 100 A 70 - 79 B 60 69 C 50 - 59 0- 49 F Your program must have an array of string objects to hold the student names and an array of int to hold the student scores. Let the teacher determines the number of students and ask the teacher to enter the information for each student. Your program should have the following programmer-defined functions: getInput () - to read the students name and scores from user getGrade () - to determine the letter grade corresponding to the score getReport () - to determine the maximum, minimum, average and standard deviation of the scores Display an error message if the teacher enter mark below 0 or above 100, and keep asking for a valid value. The program should also be capable of…2.

The cave canrepresented in a grid which has rows numbered from 1to , and of the columns numbered from 1 to . For this problem, define (?, )is the tile that is in the -th row and -column.There is a character in each tile, which indicates the type of that tile.Tiles can be floors, walls, or treasures that are sequentially representedwith the characters '.'
