Your program must:

Contain a two dimensional array to contain three student registration figures for five

different information technolory courses and a single array to contain the course

Q.2.2 Calculate and print the average of the course registration figures for each IT course

Q.2.3 Determine if the IT course will be run or not. If the average registration figures of the IT

course is greater than or equal to 70 then the IT course will run.

0.2.4 Print out each course name with the average registration and if the course will run

SOLUTION CODE

        //declare a one dimensional array to store the names of the courses
        String [] courses_names = {"Programming 101", "Web Dev 101",
        "Database 101", "Logic 101", "Management 101"};

        //We declare a two dimensional array of 5 by three
        //Rows representing the IT courses and columns representing the three students
        int[][] student_marks = {
                {50, 10, 50},

                {60, 90, 70}
        };

        //Calculate the average of each IT course
        System.out.println("\n");
        for(int i = 0; i< 5; i++)
        {
            int sum = 0;
            for(int j = 0; j<3; j++)
            {
                sum = sum + student_marks[i][j];
            }
            System.out.println("The average mark for "+courses_names[i]+" = "+(sum/3));
        }

        //Print out each course name with the
        // average registration and if the course will run
        System.out.println("\n");
        for(int i = 0; i< 5; i++)
        {
            int sum = 0;
            for(int j = 0; j<3; j++)
            {
                sum = sum + student_marks[i][j];
            }

            double average = sum/3;
            if(average >=70)
            {
                System.out.println("The average mark for "+courses_names[i]+" is "
                        +average+ " and it will run");
            }
            else
            {
                System.out.println("The average mark for "+courses_names[i]+" is "
                        +average+ " and it not will run");
            }
        }
