    Unhappy 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!!!!!

    The argument in printf statement went wrong

    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.

Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."

    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?

    The function you used goes 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++.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    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;
