Assigning a pointer to an integer

Question

Can I assign a pointer to an integer variable? Like the following.

int *pointer;
int array1[25];
int addressOfArray;

pointer = &array1[0];

addressOfAr         


        

Answer 1

Nope.

You are attempting to assign a "pointer to int" value to an "int" variable. You will get a compiler warning for sure. You could do:

int *pointer;
int array1[25];
int *addressOfArray;

pointer = &array1[0];
//The following commented lines are equivalent to the pointer assignment above and are also valid
//pointer = array
//pointer = &array[0]

addressOfArray = pointer;

This is known as a shallow copy. If you are not already familiar with the concept, I highly recommend you read it (Google "deep vs shallow copying").
