- a) Write a switch statement that assigns to the variable lumens the expected brightness of a standard light bulb whose wattage has been stored in watts. Use the following table. Assign -1 to lumens if the value of watts is not in the table. b) Write a nested if statement equivalent to the switch statement for the variable lumens. Watts Brightness (in Lumens) 15 125 25 215 40 500 60 880 75 1000 100 1675 This program is written in C Create two functions and for each part of this problem, which take as input the watts and return the brightness in lumens. Don't forget to also display the brightness value
