C++ Programming Help

I need help with a programming assignment that should prompt the user for two arguments first a DECIMAL number and second a single letter, either C or F. The decimal represents a temperature, the character represents which system that degree is in (50.0 F would be 50.0 degrees Fahrenheit). This program should take the given number and convert it to a temperature in the OTHER system. The output string format should be degree(s) is equal to degree(s) . Example: input 0 C would give the string 0.0000 degree(s) C is equal to 32.0000 degree(s) F. You can assume that either F or C will be given for input and no need to account for invalid output
