c programming language

Write a function that will read one integer from the command prompt. Your second function will decide whether the entered number is Perfect Number and Harmonic Divisor Number. The input must be a natural number. Perfect Number is the number at which the sum of all natural number divisor of a natural number n is equal to itself.(1 included, not including itself). Harmonic Divisor Number or Ore Number is a positive integer whose divisors have a harmonic mean that is an integer. Let the function continue working until it gets the '*' input then end the program. Function prototype is void decide_perfect_harmonic_number() Example: Please enter input number : 6 Natural Number Divisors: 1, 2, 3, 6 Is Perfect Number? : Yes Hint: 1+2+3=6 and input 6 . That's why it's the perfect number. Is Harmonic Divisor Number? : Yes Hint: Number 6 has the four divisors. Their harmonic mean is an integer: 4/((1/1)+(1/2)+(1/3)+(1/6))=2 Please enter input number : 28 Natural Number Divisors: 1,2,4,7,14,28 Is Perfect Number? : Yes Hint: 1+2+4+7+14=28 and input 28. That's why it's the perfect number. Is Harmonic Divisor Number? : Yes Hint: Number 28 has the six divisors. Their harmonic mean is an integer: 6/((1/1)+(1/2)+(1/4)+(1/7)+(1/14)+(1/28)=2 Please enter input number : 15 Natural Number Divisors: 1,3,5,15 Hint: 1+3+5=9 but input 15 . That's why it's not the perfect number. Is Perfect Number? : No Is Harmonic Divisor Number? : No Hint: Number 15 has the four divisors. Their harmonic mean is not an integer: 4/((1/1)+(1/3)+(1/5)+(1/15))=1.6
