Declaring dizi as int** dizi and removing the & in your loop should fix things. The reasons can be found in the following answers.
1) tdizi is an array of int*. tdizi is therefore of type int*[MAX], which will decay to int**, not to int*
2) dizi is a variable (in technical terms, it''s an lvalue), and therefore has an address. cntr1 is a variable, and therefore has an address ... but (dizi+cntr1) is not a variable (in technical terms, it''s an rvalue) and therefore doesn''t have an address.
&dizi+cntr1 will take the address of dizi (which is a local variable and NOT tdizi!) and increment it by cntr1.
&(dizi+cntr1) tries to take the address of the ''temporary variable'' that would hold the rsult of dizi+cntr1... which obviously must fail.

Your declaring your array as an array of int pointers, because arrays and pointers are related the first element is always a pointer to the next element in the array but because you are declaring the array to be an array of pointers an extra level of indirection is introduced.
