Thread: Pointer type check warning

Hi,
I have some questions about type check warning. I am reading the tutorial notes from http://www.clear.rice.edu/comp221/ht...s-pointers.pdf

CASE 1

Code:

int int1 = 1036; /* some data to point to */
int int2 = 8;
int *int_ptr1 = &int1; /* get addresses of data */
int *int_ptr2 = &int2;
*int_ptr1 = int_ptr2;
*int_ptr1 = int2;

it said "Type check warning: int_ptr2 is not an int"and "int1 becomes 8"

CASE 2

Code:

int int1 = 1036; /* some data to point to */int int2 = 8;
int *int_ptr1 = &int1; /* get addresses of data */
int *int_ptr2 = &int2;
int_ptr1 = *int_ptr2;
int_ptr1 = int_ptr2;

it said "Type check warning: *int_ptr2 is not an int *" and "Changes int_ptr1 – doesn’t change int1"
Can anyone explain?
