Test the program with these inputs: C 100 F32 C0 f0 Explain to yourself Why do the last three sets of the input values yield the same output? Why isn't c the same as C? Why would you type any number after d even though d is not a known conversion type? Fix the problems You should use two if-else structures to fix the program: One will validate the letter as soon as it is typed, ie. If the input letter is not C, c, F, or f, output "wrong letter". then use an else to skip the rest of the program (do not ask for temperature, do not print result) Do not return early. The other will choose what conversion to use. Make sure to treat (C 100) and (c 100) the same, and treat (F 32) and (f 32) the same; Use the same tests as before to confirm that you fixed the problems. When you are done: .Write comments that explain your if statements and boolean expressions. How they work? For this exercise, you will have: ex2_convert.cpp. If you have completed everything, congratulations! Please download a zip file from replit and upload it to URCourses. .
