c++ 04 数组和指针

#include <string>
#include <bitset>

using std::cin;
using std::cout;
using std::endl;
using std::string;

int ()
{
	
	const unsigned size = 3;
	int ia[size] = { 0,1,2 };
	// 使用下标遍历
	for (size_t ix = 0; ix != size; ++ix)
		cout << ix << ":" << ia[ix] << endl;
	// 使用指针遍历
	for (int *p = ia; p <  ia + size; p++)
		cout << p << ":" << *p << endl;
	// 创建动态数组
	int *pia = new int[10]; // array of 10 uninitialized ints
	int *pia2 = new int[10](); //数组初始化 0
	delete[] pia;	// 动态空间释放
	delete[] pia2;
	return 0;
