C structure pointer alignment segmentation fault question

#include <stdio.h>>
int main(void)
{
    int a[5] = {1,2,3,4,5};
    int i,j;
    for(j=0; j<5; j++) 
    {
        printf("%d\n",a[j+1]);
    }
}
//Results
2
3
4
5
0 // overflow!!

In my opinion, like the answer above, within the double for statement

When referring to records [j+1], overflow occurred for the content.

I think segmentation fault has occurred.

#include <stdio.h>>
int main(void)
{
    int *a[5] = {1,2,3,4,5};
    int i,j;
    for(j=0; j<5; j++) 
    {
        *a[j+1]='3';
    }
}

//signal: segmentation fault (core dumped)

I think Kim Ho-won's point is a problem, and the more problematic part is the lower part.

for( j = 0; i<count ; j++)

Here, j will increase indefinitely.

If you run this part in debug mode and look closely at the local variable values at the time of death, it seems that it will be solved alone. In fact, the most obvious cause of the program's death is the problem.
