1. Create a 2D char array called grades, to save the grades for three students for five courses (size 3 by 5). Write the nested for loop to initialize the first row with ‘A’, second row ‘B’, and third-row ‘C’. 2. Say the second student got C for the fifth course. The third student got an A for the first course. Make the changes to the above array. 3. Print out the array elements in the 2-dimensional format like the following. Make sure you print out the student # and course numbers so one can easily locate an array element. Format your output like the following. After initialization: Grades of 3 students Course1 Course2 Course3 Course4 Course5 Student 1: A A A A A Student 2: B B B B B Student 3: C C C C C After change: Grades of 3 students Course1 Course2 Course3 Course4 Course5 Student 1: A A A A A Student 2: B B B B C Student 3: A C C C C
