Hi friends, trying to solve this question to compute the grades of a student
A test is given where the grades are put in an answer card, whose elements can be the letters A, B, C, and D. The evaluation card is for 20 questions. Design a program that allows you to enter the test answers and store them in an array. Implement in the program a function that by reading a pattern of keys, determines the grade of a student, consider that each well answered question is 5pts, there is no negative score and there are no null and / or blank questions. The program ends after registering the grades of 10 students and at that time it must display on the screen the grades obtained by each student according to the order registered
