STL示例代码01(指针迭代器)

//STL示例 指针迭代器#include <iostream.h>#include <algorithm>using namespace std; #define SIZE 100int iarray[SIZE]; int main(){  iarray[20] = 50;  int* ip = find(iarray, iarray + SIZE, 50);//algorithm头文件中定义的一个方法,返回一个指针迭代器InputIterator  if (ip == iarray + SIZE)//如果指针指到数组的末尾,那么就没有找到    cout << "50 not found in array" << endl;  else    cout << *ip << " found in array" << endl;  return 0;}
