警告 C26495 未初始化变量 Array::a。始终初始化成员变量(type.6)。 这个程序运行没问题，但是这个警告有没有影响呀？可以解决掉么？

Question

#include
using namespace std;
const int M = 2, N = 3;
class Array {
protected:
int a[M][N];
public:
void set()
{
cout << "请输入2*3的整形数组：" << endl;
for (int i = 0; i < M; i++)
{
for (int j = 0; j < N; j++)
{
cin >> a[i][j];
}
}
}
Array()//警告 C26495 未初始化变量 Array::a。始终初始化成员变量(type.6)。

{}
Array(int a1[M][N])//警告 C26495 未初始化变量 Array::a。始终初始化成员变量(type.6)。

{
for (int i = 0; i < M; i++)
{
for (int j = 0; j < N; j++)
{

}
}
}
void show()
{
for (int i = 0; i < M; i++)
{
cout << " ";
for (int j = 0; j < N; j++)
{
cout << a[i][j] << " ";
}
cout << endl;
}
}
friend Array operator+(Array x, Array y);
friend Array operator-(Array x, Array y);
};
Array operator+(Array x, Array y)
{
Array c;
for (int i = 0; i < M; i++)
{
for (int j = 0; j < N; j++)
{

}
}
return c;
}
Array operator-(Array x, Array y)
{

for (int i = 0; i < M; i++)
{
for (int j = 0; j < N; j++)
{

}
}
return c;
}
int main()
{
int a[M][N] = { 1,2,3,4,5,6 };
Array A(a), B, C, D;
B.set();
cout << "Array A:" << endl;
A.show();
cout << "Array B:" << endl;
B.show();
C = A + B;
cout << "Array C=A+B:" << endl;
C.show();
D = A - B;
cout << "Array C=A-B:" << endl;
D.show();
return 0;
}

用a[0][0]={};初始化！
