• Aim: Write a C program to calculate the average, geometric and harmonic mean of n elements in an array.
• Code:

  //For turbo C++ remove below comments
  #include <stdio.h>
  //#include<conio.h>
  #include <math.h>
  void main()
  {
      int n,i;
      float arr[99],sum=0,g=1,h=0;
      //clrscr();
      printf("Enter length array : ");
      scanf("%d",&n);
      printf("Enter elements for array: \n");
      for (i = 0; i < n; i++){
          scanf("%f",&arr[i]);
          sum+=arr[i];
          g*=arr[i];
          h+=1.0/arr[i];
      }
      printf("Mean : %f\nGeometric Mean : %f\nHarmonic Mean : %f",sum/n,pow(g,1.0/n),n/h);
      // getch();
  }
