Question

Are the expressions arr and &arr same for an array of integers?

Answer 1

yes because both arr and &arr give the same base address of an array.
try this example :

int main() 
{
 int arr[10];
 printf("%dn",arr);
 printf("%d",&arr);
return 0;
}

Answer 2

Yes, Both are same,
Array name represents the starting address of an array

Comments

arr and &arr have same base address but arr+1 and &arr+1 are not same. arr have only base address but &arr have address of whole array.
