Hi
You must not only determine the address, but also the
data type. In fact, a vaule in a memory location can
have a different types and its correct interpretation
is not possible unless its type in known. Here is an
example for integer type:
main()
{
int *x ;
...
...
x=(int *) 0x1234 ; // Set the pointer
*x=1 ; // Set its content (integer)
}
Hope it helps
