下面的内容是不是arrayname总是指向C中第一个元素的指针？
int myArray[10] = {0};
printf("%d\n",&myArray); /* prints memadress for first element */
printf("%d\n",myArray); /* this prints a memadress too,shows that the name is a pointer */
printf("%d\n",sizeof(myArray)); /* this prints size of the whole array,not a pointer anymore? */
printf("%d\n",sizeof(&myArray)); /* this prints the size of the pointer */
