how to print 2D array code example
Example 1: how to print a 2d array in java
for (int row = 0; row < arr.length; row++)//Cycles through rows
{
for (int col = 0; col < arr[row].length; col++)//Cycles through columns
{
System.out.printf("%5d", arr[row][col]); //change the %5d to however much space you want
}
System.out.println(); //Makes a new row
}
//This allows you to print the array as matrix
Example 2: print 2d array c++
for( auto &row : arr) {
for(auto col : row)
cout << col << " ";
cout<<endl;
}
Example 3: how to print a 2d array in c++
for (int i = 0; i < m; i++)
{
for (int j = 0; j < n; j++)
{
cout << arr[i][j] << " ";
}
// Newline for new row
cout << endl;
}
