how to access individual elements in array using pointer code example

Example: accessing elements of 1d array using pointers

int main(){

    int arr[] = {1,3,4,5,6,7,8};
    int *ptr = &arr; //storing address of the first element in array in the ptr

  	//accessing the elements of the array using ptr
    for(int i=0;i<7;i++)
        printf("%d ",*(ptr+i));
  	//here i represents the value to be added to the base address
    return 0;
}
