Relationship between Arrays and Pointers

Array of pointers

C program having an array of three pointers which are assigned the addresses of three integer variables.  

#include<stdio.h> 

main() 

{ int arr[3]={1,2,3}; 

int *ptr[3],i; 

for(i=0;i<3;i++) 

{ ptr[i]=arr+i; // assigning addresses of elements to array of pointers 

} 

for(i=0;i<3;i++) 

{ printf(“\n address = %u value=%d”, ptr[i], *ptr[i]); } 

} 

Here output will be address of elements and its value. 

Address = 3219018020 value=1 

Address = 3219018024 value=2 

Address = 3219018028 value=3
