ahead : this is my start and review of c++
1.简单指针

	int a[2][5] = { { 1,2,3,4,5 },{2,4,6,8,10} };
	int(*p)[5];
	p = a;
	for (int i = 0; i < 2; i++) {
		for (int j = 0; j < 5; j++)
		{
			cout << a[i][j] <<" ";
			if (j ==4) {
				cout << endl;
			}
		}		
	}
	cout << "第一行第二列" << *(*a + 1) << endl;
	cout << "第二行第二列" << *(*(a + 1) + 1) << endl;
输出如下：
1 2 3 4 5
2 4 6 8 10
第一行第二列2
第二行第二列4
//

2.virtual的使用、虚函数与纯虚函数
3.重载运算符
