I have this program that I am using to add 4*4 matrices:
But the compiler tells meCode:#include<iostream> using namespace std; class Matrix { double x[4][4]; public: Matrix operator+(Matrix); }; Matrix::Matrix operator+(Matrix mat) { Matrix temp; for(int i = 0; i<4; i++) for(int k = 0; k<4; k++) temp.x[i][k] = x[i][k] + mat.x[i][k]; return temp; }. I don't understand how x can be private to a method that I declared within the class?Matrix::x[4][4] is private within this context
