In the above example we defined two characters (‘ch’ and ‘c’) and a character pointer ‘ptr’. First, the pointer ‘ptr’ contained the address of ‘ch’ and in the next line it contained the address of ‘c’. In other words, we can say that Initially ‘ptr’ pointed to ‘ch...
an array of pointers is a data structure in which the elements of the array are pointers. instead of holding data directly, each element in the array holds the memory address (pointer) of another data element. this allows for the creation of an array where each element can point to a ...
printf ("%d \t", *p[i]); //printing array of pointers getch(); } Output elements at the array are : 10 20 30 Pointer to Pointer Pointer to pointer is a variable that holds the address of another pointer. Declaration datatype ** pointer_name; For example, int **p; //p is a...
In the above example I have used &val[i] to get the address of ith element of the array. We can also use a pointer variable instead of using the ampersand (&) to get the address. Example – Array and Pointer Example in C #include<stdio.h>intmain(){/*Pointer variable*/int*p;/*A...

If you add size of variable to the pointer (for example arr + sizeof(str)), the pointer will point to the next variable in the array ( arr == &arr[1] and *arr == arr[1] ).You can create array in several ways:1. Dynamic array allocated with intrinsic memory-allocation functions...
