23.
If the size of integer is 4bytes, What will be the output of the program?
#include<stdio.h>
int main()
{
int arr[] = {12, 13, 14, 15, 16};
printf("%d, %d, %d\n", sizeof(arr), sizeof(*arr), sizeof(arr[0]));
return 0;

The answer will respect with bitwise.
If 16 bit then 10, 2, 2.
If 32bit then 20, 4, 4. Here we assume that it is 32bits.

What if the array was declared as
int *arr[] = { 1,2,3,4,5 } ;
What would sizeof(arr) return ?
int *arr[] = { 1,2,3,4,5 } ;
What would sizeof(arr) return ?

It is given in the question. that int is of 4 bytes, so multiply by 4 and not 2

By size of array, it means the no of elements it can have rather than the complete size.

Why multiply by 4 it should be 2?
