Answer 1

You decleared array which type is int and it can store 5 integer becoz you wrote size 5 . It will be better to write like this when u defining multiple elements
int a[ ]= {22,33,44,55,66}; here you dont need to declear size of array it will take automatically according to your elements.
In next line you decleared pointer ptr which will point int type values .
In next line u wrote
ptr =&a[0] ; here a[0] representing the first index of array address if u will print first value 22 then
& a[0] it will print address . If u write &a[1] then it will print the address of next element .
You asking how to print address of all elements then you can write in loop or u can write single single statements .
I used loop

#include <stdio.h>

int main() {
int a[ ] = {22, 33, 44, 55, 66};
int *ptr = NULL;
for(int i=0;i<5;i++)

{
ptr = &a[i];
printf("\n%p",ptr);
}

}

Thank you codemonkey 😊

Answer 3

codemonkey then how can find the address of whole array.?
can I able to find it?
i.e int a[5]

Answer 4

codemonkey you mean address of array (i.e int a[ ])
Is same for first array element address (i.e a[0])
Am I right ?
if yes means,can you give me reason for that.....
