#include<stdio.h>
#define SIZE 4
int main(void){
   
    short dates[SIZE];
   
    double index;
    short *pti;
    double bills[SIZE];
    double *ptf;

    pti=dates;
    ptf=bills;
    printf("%23s %10s","short","double");
    for(index=0;index<SIZE;index++)
        printf("pointer + %d: %10P %10p\n",index,pti+index, ptf+index);
    return 0;
}

指针：double *ptf;short *pti;
编译出错error C2111: pointer addition requires integral operand
    求大神帮解决。
