C – Array Internal Pointer

Array internal pointer representation:

• Generally, we access elements of array using their index.
• For example, arr[i]
• The expression arr[i] converts into *(arr+i)

#include<stdio.h> int main() {             int arr[5] = {10, 20, 30, 40, 50}, i;                      printf(“Array elements are : \n”);             for(i=0 ; i<5 ; i++)                         printf(“%d\n”, arr[i]);               printf(“Array elements are : \n”);             for(i=0 ; i<5 ; i++)                         printf(“%d\n”, *(arr+i));             return 0; }

In multiple ways, we can access the elements of array:

#include<stdio.h> int main() {             int arr[5] = {10,20,30,40,50};             int i;             printf(“Array elements are : \n”);             for(i=0 ; i<5 ; i++){                         printf(“%d, %d, %d, %d \n”, arr[i], *(arr+i), *(i+arr), i[arr]);             }             return 0; }
