c语言之指针与数组

int main()
{
int i=10;
int *p=&i;
int **pp=&p;
int ***ppp=&pp;
cout<<p<<":"<<*p<<":"<<endl;
cout<<pp <<":"<<*pp<<":"<<**pp<<":"<<endl;
cout<<ppp<<":"<<*ppp<<":"<<**ppp <<":" <<***ppp<<":"  <<endl;
return 0;
}

void main()
{
int a[3][3]={ 1,2,3,4,5,6,7,8,9};
int (*q)[3];//数组指针

q=a;
cout<<q<<endl;//0012ff24
cout<<*q<<endl;//0012ff24
cout<<*q+1<<endl;//0012ff28//p+4bit
cout<< *q[0]<<endl;//1
cout<< **q <<endl;//1  等同上
cout<<**q+100<<endl;//101
cout<<**(q+1)<<endl;//4
cout<<*(*q+1)<<endl;//2
cout<<q+1<<endl;//0012ff30
cout<<*(q+1)<<endl;//0012ff30
cout<<q+3<<endl;//0012ff48,
cout<<*q+1<<endl;

int *q[3];//指针数组
for(int i=0;i<3;i++)
q[i]=a[i];
cout<<q<<endl;//ff18   q本身
cout<<*q<<endl;//ff24   a[0][0]地址
cout<<*q+1<<endl;//ff28 a[0][1]
