Calculating the average of an array entered by the user.

Hello. Im having trouble calculating the average of an array. Ill get right to it and post my code.

Code:

int main(void)
{
    float *list,average = 0, sum = 0;
    int sortnum, j, arrayinput;
    printf("Enter the number of data points to average: ");
    scanf("%d",&sortnum);
    list = malloc(sortnum * sizeof(int));
    
    for (j = 0; j < sortnum; j++)
        scanf("%f", list + j);
    
    printf("You entered the following:\n");
    
    for (j = 0; j < sortnum; j++)
        printf("%f\n", *(list + j));
    
    free(list);
    
    sum  = *list + sortnum;
    average = sum/sortnum;
    printf("Average %d", average);



    return 0;

}

When I run the program everything works fine, except the average is always 0. Any help will be appreciated.
Thanks

Is this supposed to be C or C++?

Anyway, I note that you access *list after free(list), which is wrong. In terms of algorithm, you don't actually sum the elements of the array, so your calculation is off.

I think if you take a long, hard look at this line, you'll see where your error is:

sum = *list + sortnum;
