【C++】不同模板对象之间赋值

---

代码：

#include <iostream>
using namespace std;

template<class _Ty>
class object
{
public:
	_Ty _val;
public:
	object(_Ty val = 0) : _val(val)
	{}
	template<class other>
	object& operator=(const object<other>& src)
	{
		if (this != (object<_Ty>*) (&src))
		{
			this->_val = (_Ty)src._val;
		}
		return *this;
	}
};

int main()
{
	object<int> obja(10);
	object<double> objb(20);
	obja = objb;
	cout << obja._val << endl;
	return 0;
}

结果：
