如果两个指针变量指向同一个变量，那么这两个指针的地址则一定相同吗？
#include <iostream>using namespace std;
int main(void)
{
int a = 1;
int b = 1;
int *pa = &a;
int *pb = pa;
int *pc = &a;
int *pd = &b;
printf("Address of pa is %p, and address of what pa points is %p\n", pa, &(*pa));
printf("Address of pb is %p, and address of what pb points is %p\n", pb, &(*pb));
printf("Address of pc is %p, and address of what pc points is %p\n", pc, &(*pc));
printf("Address of pd is %p, and address of what pd points is %p\n", pd, &(*pd));
return 0;
}
输出：
Address of pa: 0x7fff8bada600, address of what pa points: 0x7fff8bada600
Address of pb: 0x7fff8bada600, address of what pb points: 0x7fff8bada600
Address of pc: 0x7fff8bada600, address of what pc points: 0x7fff8bada600
Address of pd: 0x7fff8bada604, address of what pd points: 0x7fff8bada604
