c语言中指针运算符和下标运算符

#include <stdio.h>

int main(void)
{
    int i;
    int a[5] = {1,2,3,4,5};
    int *p = a;
    
    for(i = 0; i < 5; i++)
    {  //alias elements a[i].  *(a+i).  *(p+i).  p[i]
        printf("a[%d] = %d || *(a + %d) = %d || *(p + %d) = %d || p[%d] = %d\n", i, a[i],  i,*(a + i),  i,*(p + i),  i,p[i]);
    }
       
    puts("\n\n========================================================\n\n");
    for(i = 0; i < 5; i++)
    {    //corresponding pointer： &a[i], a+i,  p+i, &p[i]
        printf("&a[%d] = %p || a + %d = %p || p + %d = %p || &p[%d] = %p\n", i,&a[i],  i, a+i,  i,p+i, i,&p[i]);
    }
