Two Dimensional Array Implementation Using Double Pointer
2D array with double pointers that means that you have a main array and the elements of the main array are pointers or addresses to a sub arrays As indicated in above figure so if you have defined a double pointer as a pointer of this 2D array let s say int ptr so ptr is ponting to the main array which will contains pointers to sub arrays
