12. The table below lists approximations in meters of the longest wavelengths in each region of the electromagnetic spectrum. The final column gives these m lengths as they would be represented in C scientific notation. You can see that the "E" would be read as "times 10 to the power." Numbers in this format can be used as constants. They can be scanned in using the %lf placeholder. However, to output a number in scientific notation, use the %e placeholder. Note that visible light makes up a tiny fraction of the full spectrum. Write a program that repeatedly prompts the user to enter a wavelength in scientific notation (or zero to quit) and displays for each entry the wavelength and the region of the spectrum into which it falls. Note that zero is used as a sentinel, so no region should be displayed when the user enters zero.

12. The table below lists approximations in meters of the longest wavelengths in
each region of the electromagnetic spectrum. The final column gives these
m lengths as they would be represented in C scientific notation. You can see that
the "E" would be read as "times 10 to the power." Numbers in this format
can be used as constants. They can be scanned in using the %lf placeholder.
However, to output a number in scientific notation, use the %e placeholder.
Note that visible light makes up a tiny fraction of the full spectrum. Write a
program that repeatedly prompts the user to enter a wavelength in scientific
notation (or zero to quit) and displays for each entry the wavelength and the
region of the spectrum into which it falls. Note that zero is used as a sentinel,
so no region should be displayed when the user enters zero.
