Segmentation fault (core dumped)

The following program accidentally writes Parr as a *parr in 11 rows scanf (), which is not a problem at compile time, but appears at run time:

[Lujinhong@lujinhong chapter12]$ gcc reverse3.c
[Lujinhong@lujinhong chapter12]$./a.out
Enter number:19 76 8 93 766 8 6 934 0-3
Segmentation fault (core dumped)

#include <stdio.h>

#define ARRAY_SIZE

int main (void) {

    int arr[array_size], *parr;

    printf ("Enter%d number  :", array_size);
    for (Parr=arr; parr<arr+array_size; parr++) {
        scanf ("%d", *parr);
    }

    printf ("The number would output in reversal order:\n");
    for (parr=arr+array_size-1; parr>=arr; parr--) {
        printf ("%d\t", *parr);
    }
    printf ("\ n");

    return 0;

Segmentation fault (core dumped) is generally caused by improper memory operation, and it is common to:

(1) The array is out of range.

(2) Read-only memory has been modified.

(3) This example also modifies the read-only memory.
