#include <stdio.h>
int main()
{
int arr[5];
// Assume base address of arr is 2000 and size of integer is 32 bit
printf("%u %u", arr + 1, &arr + 1);
return 0;
}
What is the o/p of the program?
2004 2020
2004 2004
2004 Garbage value
The program fails to compile because Address-of operator cannot be used with array name
#include<stdio.h>
void fun(int **p);
int main()
{
int a[3][4] = {1, 2, 3, 4, 4, 3, 2, 8, 7, 8, 9, 0};
int *ptr;
ptr = &a[0][0];
fun(&ptr);
return 0;
}
void fun(int **p)
{
printf("%d\n", **p);
}
