Temperature Macros
MediumDefine two fully parenthesized function-like macros above main: CELSIUS_TO_F(c), which converts Celsius to Fahrenheit as ((c) * 9.0 / 5.0) + 32.0 with the whole body in one more pair of parentheses, and MAX2(a, b), which yields the larger of its two arguments with ?:. Read two Celsius temperatures with one guarded scanf ("%lf %lf"); on bad input print "invalid input" and return 1. Convert each temperature exactly once into a variable, then print both Fahrenheit values and the warmer of the two, each to one decimal place. Passing the converted variables, not nested macro calls with side effects, to MAX2 is the point of the exercise.
