I know how to allocate 2D array but dynamically allocation is not clear. Would be thankful if someone will answer.
Following are different ways to create a 2D array on heap (or dynamically allocate a 2D array).
In the following examples, we have considered ‘r‘ as number of rows, ‘c‘ as number of columns and we created a 2D array with r = 3, c = 4 and following values
1 2 3 4
5 6 7 8
9 10 11 12
