C++一维数组和指针的关系总结.doc

C+一维数组和指针的关系总结对于数组int a10;a表示数组的第一个元素的地址，即&a0;如果使指针p，指向数组的首元素，可以进行操作：int * p=a;或者int *p=&a0;那么p+，是指向数组中的先一个元素，即a1;此时*p则是a1中所放的值。此时，ai=pi=*(a+i)=*(p+i)下面举一个例子；直接用ai来输出#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;for(i=0;i10;i+)coutai ;coutendl;return 0;#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;for(i=0;i10;i+)coutai ;coutendl;return 0;用*(a+i)来输出#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;for(i=0;i10;i+)cout*(a+i) ;coutendl;return 0;#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;for(i=0;i10;i+)cout*(a+i) ;coutendl;return 0;用*(p+i)来输出#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;int * p=a;for(i=0;i10;i+)cout*(p+i) ;coutendl;return 0;#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;int * p=a;for(i=0;i10;i+)cout*(p+i) ;coutendl;return 0;关于*p+由于+和*的优先级相同，结合方向是自右而左，因此它等价于*(p+)。作用是：先得到p指向的变量的值（即*p），然后再使指向p的值加1.#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;int * p=a;while(pa+10)cout*p+t;coutendl;return 0;#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;int * p=a;while(pa+10)cout*p+t;coutendl;return 0;等价于#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;int * p=a;while(pa+10)cout*pt;p+;coutendl;return 0;#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;int * p=a;while(pa+10)cout*pt;p+;coutendl;return 0;*p+等价于*(p+);而*(+p)表示先使p+1,再取*p.#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input 10 intergers: endl;int i=0;int * p=a;while(pa+10)cout*(+p)t;coutendl;return 0;#includeusing namespace std;int main()int a10=1,2,3,4,5,6,7,8,9,10;coutPlease input
