C program compile but not doing the calculations

Hello all,
I wrote a C program and I compile with Miracle C - a C compiler software, the program was compiled successfully but does not do any calculations under it. All the calculations I put there was not done, I included math.h and stdio.h, is there anything I am doing wrong??

Below is the program:

Code:

---

/* program to calculate the geometric and arithmetric average of a set of numbers*/
#include <stdio.h>
#include <math.h>
main()
{
  float y, x, xavg, xavg1, temp=1.0, sum=0.0;
  int count=1, n;
  printf ("\nEnter the total items to calculate\n");
  scanf ("%d", &n);
  while (count<=n)
    {
    printf ("\nEnter x\n");
    scanf ("%f", &x);
    temp*=x;
    sum+=x;
    ++count;
    };
  y = 1/n;
  xavg= pow(temp, y);
  xavg1= sum/n;
  printf ("\nThe geometric average is %f\n", &xavg);
  printf ("\nThe arithmetric average is %f\n", &xavg1);
}

---

I need help urgently!!!!!

Remove the '&' in printf statement for the variables

Thank you so much, it works.

But i want to calculate x^y(x raise to power y) and dont how to write the statement in C, anyone here to help?

You do know how (you just might not realize it), you did it here:

Code:

---

xavg= pow(temp, y);

---

So apply that knowledge to what you are trying to do.

I did that but I am not getting the correct answer, I use my calculator and I got a different answer. No matter the values I entered I got 1.00 as answer or maybe I am doing something wrong?

FYI

#include <math.h>

double pow(double x, double y);

float powf(float x, float y);

long double powl(long double x, long double y);


So try to change code as per your requirement.

Well there's your problem, this is a toy, not a C compiler.

Trust me, it won't take long before you realise that it's a PoS.
Just do yourself a big favour and get dev-C++.

Code:

---

float y, x, xavg, xavg1, temp=1.0, sum=0.0;
int count=1, n;
...
y = 1/n;

---

That's another problem, integer division (1 divided by an integer n) results in an integer which is then assigned to a float. You need to adjust that calculation a bit so that you are doing floating-point division:

Code:

---

y = 1.0 / n;

---

Thank you a lot. I have done it and is working. I so much appreciate your effort in helping me solve this problem.
