#include <iostream>

int main(){
	int m[3][3] = {
		{0,1,2},
		{3,4,5},
		{6,7,8},
	};

	for(int K=0; K<3; ++K){
		for(int L=0; L<3; ++L)
			std::cout << m[K][L] << ' ';
		std::cout << '\n';
	}

	std::cout << "-----\n";

	for(auto &row: m){
		for(auto &value: row)
			std::cout << value << ' ';
		std::cout << '\n';
	}
}
