Description

Calculate harmonic mean of two numbers which is taking the inverses of the two numbers, averaging them, and taking the inverse of the result.

Demo Code

#include <stdio.h>

double harmonic_mean(double, double);

int main(void)
{
  double x, y;/*  ww  w .j a v  a 2  s.  c  om*/

  printf("Enter two numbers: ");

  while (scanf("%lf %lf", &x, &y) == 2){
    printf("%f\n", harmonic_mean(x, y));

    printf("Enter two numbers: ");
  }

  return 0;
}

double harmonic_mean(double x, double y)
{
  return 2 / (1 / x + 1 / y);
}
