我的老师在他的演讲幻灯片上有这些问题,但没有答案。有人可以帮忙吗。新来的c。
If a is an int variable, is it always true that *&a == a ?
If p is an int* variable, is it always true that p == &*p ?
Is it ever meaningful to say **p ?
Is it ever meaningful to say &&a ?
After assigning a = 2 and p = &a, how much is *p**p ?
If furthermore q = &p, how much is **q**p***q ?
最后, a/*p 多少钱?
