print 2d vector c++

	for(int i=0; i<v.size(); i++) 
		for(int j=0; j<v[i].size(); j++) 
  			cout<<v[i][j]<<" ";
        cout<<endl;

print 2d array c++

for( auto &row : arr) {
    for(auto col : row)
         cout << col << " ";
	cout<<endl; 
}

print two dimensional array c++

//this way you can print your array row by row
for (int i = 0; i < row; i++){
	for (int j = 0; j < column; j++){
		cout << array[i][j];
	}
}

//this way you can print your array column by column

for (int i = 0; i < column; i++){
	for (int j = 0; j < row; j++){
		cout << array[i][j];
	}
}

print 2d array

2-D Vectors


vector<vector<int>> vect;

for (int i = 0; i < vect.size(); i++)
    {
        for (int j = 0; j < vect[i].size(); j++)
        {
            cout << vect[i][j] << " ";
        }   
        cout << endl;
    }

how to print out a two dimensional array in c++

    for(int row=0; row<=3; row++){

      for(int col=0; col<=2; col++){
       Serial.print(buff[row][col]);
       delay(200);
      }
       Serial.println();
    }
