自己写数据结构

#include<iostream>
#include<array>
template<typename T,size_t S>
class Array {
private:
	T m_data[S];
public:
	constexpr int Size()const {
		return S;
	}
	T& operator[](int index) { return m_data[index]; }
	const T& operator[](int index) const { return m_data[index]; }
	T* Data() { return m_data; }
	const T* Data()const { return m_data; }
};
int main() {
	int size = 10;
	Array<int, 10>data;
	//static_assert(data.Size() < 8, "Size is too large!");
	const auto& newdata = data;
	memset(data.Data(), 0, data.Size() * sizeof(int));
	for (int i = 0; i < data.Size(); i++) {
		data[i] = 2;//data[i]是左值
		std::cout << newdata[i] << std::endl;
		
	}
}
