Pointers & 2D array in C programming

Pointers & 2D array in C programming

As we know that the one dimensional array name works as a pointer to the base element (first element) of the array. However in the case 2D arrays the logic is slightly different. You can consider a 2D array as collection of several one dimensional arrays.

#include <stdio.h>
int main()
{
   int abc[5][4] ={
            {2,4,6,8},
            {10,12,14,16},
            {18,20,22,24},
            {26,28,30,32},
            {34,36,38,40}
            };
    for (int j=0; j<=4; j++)
    {
        /* The correct way of displaying an address would be
         * printf("%p ",abc[j]); but for the demonstration
         * purpose j am displaying the address in int so that
         * you can relate the output with the diagram above that
         * shows how many bytes an int element uses and how they
         * are stored in contiguous memory locations.
         *
         */
    	printf("%d ",abc[j]);
    }
    return 0;
}
