Can C++ have two-dimensional object arrays?
In C++, we can create an array of an array, known as a multidimensional array. For example: int x[3][4]; Here, x is a two-dimensional array.
How do you declare a 2D array?
Two – dimensional Array (2D-Array)
- Declaration – Syntax: data_type[][] array_name = new data_type[x][y]; For example: int[][] arr = new int[10][20];
- Initialization – Syntax: array_name[row_index][column_index] = value; For example: arr[0][0] = 1;
