kExercise 5.4 Table of reciprocals, squares, cubes, and fourth powers.
Exercise 5-4. Define a two-dimensional array, data[11][5] , of type double. Initialize
the elements in the first column with values from 2.0 to 3.0 inclusive in steps of 0.1.
If the first element in a row has value x, populate the remaining elements in each row
with the values 1/x, x2, x3, and x4 . Output the values in the array with each row on a
separate line and with a heading for each column.
