You MUST use switch statement to complete the following. Write a program to achieve a four-function calculator. The program will first take two real (non-zero) numbers as input from the user. You can safely assume the user will always input two numbers. The program then outputs the following message to prompt another user input:

Please select:
: add two numbers.
-: subtract two numbers.
*: multiple two numbers.
/: divide two numbers.

The user then enters one of the above characters for the program to perform the corresponding calculation on the previously two numbers. If the user enters other character than the above, the program will print out Unknown calculation and exits.

Ex: if the user enters: 2.5 4 *
the program will output: 2.5 * 4

Sorry i don’t know the answer to this

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !
