lab7.cpp:126: invalid conversion from `int*' to `int'
lab7.cpp:128: invalid conversion from `int' to `int*'

Code:

 126                                int tmp = *(&a+cnt);
 127                                *(&a+cnt) = *(&a+cnt+1);
 128                                *(&a+cnt+1) = tmp;

am I missing anything, this should be practically obvious.

126 your trying to store a pointer in an integer
128 your trying to store an integer in a pointer

pretty obvious to me what is wrong...

Yes, but i'm dereferencing, i hope.

Pointers are not the actual value but a pointer to the value. If you do not understand this you should look at a learning C or C++ site as this is very important.
