为什么*p[1] 指不到值?
int main()
{

float V[3]={0,10,20};
float* pV = V;
cout < < "*V " < < *V < < endl;
cout < < "*(V+1) " < < *(V+1) < < endl;
cout < < " V " < < V < < endl;
cout < < "&V " < < &V < < endl;
cout < < "pV " < < pV < < endl;
cout < < "pV[0] " < < pV[0] < < endl;
cout < < "pV[1] " < < pV[1] < < endl;
cout < < endl;

float(* p)[3] = &V;
cout < < " p " < < p < < endl;
cout < < "*p " < < *p < < endl;
cout < < "*p[0] " < < *p[0] < < endl;
cout < < "*p[1] " < < *p[1] < < endl;
cout < < "*p[2] " < < *p[2] < < endl;
cout < < "**(p+1) " < < *(*p+1) < < endl;
cout < < "**(p+2) " < < *(*p+2) < < endl;
cout < < " p[0] " < < p[0] < < endl;
cout < < " p[1] " < < p[1] < < endl;
}

// cout < < "*p[1] " < < *p[1] < < endl;
//cout < < "*p[2] " < < *p[2] < < endl;
指不到值.

[解决办法]
cout < < "*p[0] " < < (*p)[0] < < endl;
cout < < "*p[1] " < < (*p)[1] < < endl;
cout < < "*p[2] " < < (*p)[2] < < endl;
[解决办法]
一维数组
*(p+n) = p[n]
