1 #include <iostream>
2 using namespace std;
3
4 int main ()
5 {
6 char c[5] = "hell";
7 int i[5] = {1,2,3,4,5};
8 char a = 'o';
9
10 char(*p1)[5] = &c;
11 char* p2 = c;
12 int(*p3)[5] = &i;
13 int* p4 =i;
14 char* p5 = &a;
15
16 cout << "p1=" << *p1 << endl;
17 cout << "p2=" << *p2 << endl;
18 cout << "p3=" << *p3 << endl;
19 cout << "p4=" << *p4 << endl;
20 cout << "p5=" << *p5 << endl;
21 return 0;
22 }
输出结果为：
p1=hell
p2=h
p3=0xbfa401b0
p4=1
p5=o

p1=&c => *p1就是c
p2=c => *p2就是c[0]
p3=&i => *p3就是i
p4=i => *p4就是i[0]
p5=&a => *p5就是a
