Why this code leads to segmentation fault?

Question

1) In CS50 ide, it does not even compile giving error: format specifies type

'int *' but the argument has type 'int' [-Werror,-Wformat]
        scanf (" %d", array[n]);

2) In codeblocks, it runs and I am able to read in to howMany variable but then gives seg fault after it asks for the first number to be read

# include <stdio.h>
# include <stdlib.h>

int main(void)

{

    int n, howMany;
    float total = 0;
    float average = 0;

    printf(" How many numbers you want to Enter\n");
    scanf(" %i", &howMany);

    int array[howMany];

    for (n=0; n < howMany; n++)
    {
        printf("enter a number: ");
        scanf (" %d", array[n]);
        total += array[n];
    }
    average = total/howMany;
    printf ("average of all numbers entered is %f\n", average);


}

Answer 1

Ok got it, I had to write &array[n], I had skipped it thinking array is already a pointer.
