指针加减法

//本次代码告诉你指针加上一个整数是怎么回事
#include
#define SIZE 4
int main()
{
	short dates[SIZE];
	short *pti;
	short index;
	double bills[SIZE];
	double *ptf;
	pti = dates;
	ptf = bills;
	printf("%23s,%15s\n", "short","double");
	for (index = 0; index < SIZE; index++)
		printf("pointers +  %d: %10p    %10p\n",index,pti +index,ptf+index);
	return 0;
		

}
