One of the most common methods to return a 2D array from a function in C++ is by using pointers. This method involves dynamically allocating memory for your array and returning a pointer to that memory. Here’s
Here is an example of how to get the length of a 2D array in Java: int[][]array={{1,2,3},{4,5,6},{7,8,9}};intnumRows=array.length;intnumColumns=array[0].length;System.out.println("The array has "+numRows+" rows "+"and "+numColumns+" columns."); The code above gets ...
