Predict the output of below program:

#include

 

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;

}

Name of array in C gives the address(except in sizeof operator) of the first element. Adding 1 to this address gives the address plus the sizeof type the array has. Applying the Address-of operator before the array name gives the address of the whole array. Adding 1 to this address gives the address plus the sizeof whole array.
