C语言二维数组与指针-创新互联

#includeint main()
{
    char a[2][16]={0};
    printf("a=%p\na[0]=%p\na[0][0]=%p\n",a,a[0],a[0][0]);
    printf("\n");
    printf("&a=%p\n&a[0]=%p\n&a[0][0]=%p\n",&a,&a[0],&a[0][0]);
    printf("\n");
    printf("*a=%p\n**a=%p\n*a[0]=%p\n",*a,**a,*a[0]);
    printf("\n");
    printf("a+1=%p\na[0]+1=%p\na[0][0]+1=%p\n",a+1,a[0]+1,a[0][0]+1);
    printf("\n");
    printf("&a+1=%p\n&a[0]+1=%p\n&a[0][0]+1=%p\n",&a+1,&a[0]+1,&a[0][0]+1);
    printf("\n");
    printf("*a+1=%p\n**a+1=%p\n*a[0]+1=%p\n",*a+1,**a+1,*a[0]+1);

}

运行结果：

a=000000000061FE00
a[0]=000000000061FE00
a[0][0]=0000000000000000

&a=000000000061FE00
&a[0]=000000000061FE00

*a=000000000061FE00
**a=0000000000000000
*a[0]=0000000000000000

a+1=000000000061FE10
