C++ 类模板与无类型参数

使用无参数类型的类模板

#include<iostream>
using namespace std;

template <class T, int size=10>
class A
{
	T *p;
	public:
		A(T* q)
		{
			p = new T[size];
			for(int i=0;i<size;i++)
				p[i] = *q++;
		}
		void disp()
		{
			int i;
			for(i=0;i<size;i++)
				cout<<p[i];
			cout<<endl;
		}
};

int main()
{
	int a[] = {1,2,3,4,5,6,7,8};
	char* b = "abcdefghijkl";
	A<int, 5> s1(a);
	cout<<"a:";s1.disp();
	A<char> s2(b);
	cout<<"b:";s2.disp();
	return 0;
}
