19, 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any data type you wish. The program should have the following functions: r getTotal. total function should accept array array as its argument and a two-dimensional of all the values in the This return the get Average. This function should accept a two-dimensional array as its argument and return the average of all the values in the array getRowTotal. This function should accept a two-dimensional array as its first argu- ment and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. get column Total. This function should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. getHighestInRow. This function should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the highest value in the specified row of the array. getLowestInRow. This function should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the lowest value in the specified row of the array. Demonstrate each of the functions in this program
