#include <stdio.h>

    int main(void)
    {

        int * restrict p1;
        p1 = a;
        printf("%d\n",p1[2]);
   
        int b[3];
        int * restrict p2;
        p2 = b;
        b[2] = 5;
        printf("%d\n",p2[2]);
        p2 = b;
   
        int * restrict p3 = (int *)malloc(10*sizeof(int));//不能写成int restrict * p3 = (int*)malloc(10*sizeof(int));
        int * p4 = p3;
        p3[3] = 10;
        p3[3] += 10;
        printf("%d\n",p3[3]);
        p4[3] = 11;
        p3[3] += 10;
        printf("%d\n",p3[3]);
        printf("%d\n",p4[3]);
        return 0;
    }
结果：
    3
    5
    20
