The code performs one overall task: compute the mean of all scores in the class, and set the color each seat according to its value. The operation is broken down into these steps: Examine each text box in the classroom, and: collect its current value convert the value to an integer assign the value to the corresponding element in the 2-D ‘scores’ array add the value to a ‘total ‘score variable Divide the ‘total’ of the scores by the number of seats to obtain the mean Display mean score value on the screen in  output text box Visit each text box in the classroom, and Determine the proper color for the seat based on its value and calculated mean: If less than mean, color is red If between mean and 90%, color is yellow If greater than 90%, color is green Set background color of seat textbox to the proper color Note: The ‘Tag’ property of each seat’s textbox was set to string “Seat” at design time (manually), to reflect the row/column position of the seat. This allows us to tell seats apart and relate them to row/column positions in the 2-D scores array. The FindBox() method implements this functionality.

The provided code is intended to compute the mean of all scores in a classroom and set the color of each seat based on its value. The code achieves this by following a series of steps:

1. Examination of each text box in the classroom: The code iterates through each text box and performs the following operations on each box.

2. Collection of current value: The code collects the current value of each text box.

3. Conversion of value to an integer: The code converts the collected value to an integer data type.

4. Assignment of value to the corresponding element in the 2-D ‘scores’ array: The code assigns the converted value to the appropriate element in the 2-D array named ‘scores’. This allows for the aggregation of all scores.

5. Addition of value to a ‘total’ score variable: The code adds the value to a ‘total’ variable, which keeps track of the sum of all scores.

6. Division of the ‘total’ of the scores by the number of seats: The code divides the sum of all scores by the number of seats in the classroom. This computation results in the mean score.

7. Display of mean score value on the screen: The code outputs the mean score value in an output text box on the screen.

8. Visit to each text box to determine the proper color for the seat: The code iterates through each text box again to assess its value and calculate the mean.

9. Determination of the proper color for the seat based on its value and calculated mean: Based on the seat’s value and the calculated mean, the code determines the appropriate color for the seat. If the seat’s value is less than the mean, the color is set to red. If the seat’s value is between the mean and 90%, the color is set to yellow. If the seat’s value is greater than 90%, the color is set to green.

10. Setting of background color of seat textbox to the proper color: After determining the appropriate color, the code sets the background color of the seat’s textbox accordingly.

It is important to note that the ‘Tag’ property of each seat’s textbox was set to the string “Seat” at design time manually. This property assists in distinguishing seats and relating them to their corresponding row and column positions in the 2-D ‘scores’ array. The ‘FindBox()’ method is responsible for implementing this functionality.
