C语言指向数组的指针

#include <stdio.h>

int main () {

   /* an array with 5 elements */
   double balance[5] = {1000.0, 2.0, 3.4, 17.0, 50.0};
   double *p;
   int i;

   p = balance;

   /* output each array element's value */
   printf( Array values using pointer\n);

   for ( i = 0; i < 5; i++ ) {
      printf(*(p + %d) : %f\n,  i, *(p + i) );
   }

   printf( Array values using balance as address\n);

   for ( i = 0; i < 5; i++ ) {
      printf(*(balance + %d) : %f\n,  i, *(balance + i) );
   }

   return 0;
}
