Assignment 4 - matrix functions

struct Matrix {
	int** array;
	int rows;
	int cols;
};

void createMatrix( Matrix& m, int rows, int cols );
void deleteMatrix( Matrix& m );
void inputMatrix( Matrix& m );
void outputMatrix( Matrix& m );
void copyMatrix( Matrix& dest, const Matrix& src );
void addMatrix( Matrix& lhs, const Matrix& rhs );

implement the above functions
