Write a program which requests two lengths in feet and inches (both whole numbers) and prints the sum of the lengths in feet and inches. For example, if the lengths are 5 ft. 4 in. and 8 ft. 11 in., your program should print 14ft. 3 in. (1 ft. = 12 in.) Your program must use a function that takes 4 parameters  (2 for the feet and inches of the first length, and 2 for the feet an inches of the second length). The function must return a string with the answer. below is my code and l would like it to use a function that takes 4 parameters and also the function must return a string with the answer.

            ftotal = ftotal + 1;
        }

        Console.WriteLine("\n The total feet is "); Console.WriteLine(ftotal);
        Console.WriteLine("\n The total inches is "); Console.WriteLine(itotal);
