Copper has a specific heat of 0.382 J/g0C. The temperature of an unknown mass of copper increases by 4.500C when it absorbs 3.97 J of heat. What is the mass of the copper?
Create a program that will transpose the elements (values) of a 16-element two-
dimensional integer array (4x4) Transpose. The value of each element should be obtained
from the user (or inputs).
For example:
Original Entries Transposed Entries
1 2 3 4 1 5 9 3
5 6 7 8 2 6 0 4
9 0 1 2 3 7 1 5
3 4 5 6 4 8 2 6
