which is not necessarily true. Empty will randomly select spaces from the memory to return, and there is no guarantee that there are no values in these spaces. So after we use empty to create the array, before using it, we must remember to initialize them. ...

A 2D array is also known as a matrix (a table of rows and columns).To create a 2D array of integers, take a look at the following example:int matrix[2][3] = { {1, 4, 2}, {3, 6, 8} }; The first dimension represents the number of rows [2], while the second dimension ...
