c programming

12. The harmonic mean of two numbers is obtained by taking the inverses of the two numbers, averaging them, and taking the inverse of the result. Write a function called harmonic that takes two double arguments and returns the harmonic mean of the two numbers. The function must receive the two values as arguments. Read the two values from the user in the main function. Example When the input is: 9.842 1.2 The output is: 2.1392 Requirements Read the inputs from the user Declare the prototype of your function before the main function Call your function to compute the result Print out the result using the "1.41f" format 11 any of the inputs is zero, consider the inverse of that input to be well. If both inputs are zero return 0. as
