i tried find location of crusor array of 1896(becomes whole console in 2d, 79*24). took location , divided 79. mov ax, [y-16h] dec ax mov bx, 79 div bx mov z, dl add z, dh mov dl, z mov z, al add z, ah mov dh, z i overflow error. can tell me doing wrong please? maybe suggest solution? div bx divides 32-bit number formed dx (high word) , ax (low word) bx . therefore need clear dx (e.g. xor dx,dx ) prior division avoid overflow. by way, sure don't want divide 80? i've never heard of 79-column console, although i'm no expert on such matters

from documentation of new : the first version (1) throws bad_alloc if fails allocate storage. otherwise, throws no exceptions (no-throw guarantee). to me, should mean code #include <new> struct a{ a(){ throw 0; } }; int main(){ try{ a* = new a; } catch(std::bad_alloc&){} } is fine. however, when compiling gcc (see here ), program terminates after throwing int . that's documentation of operator new , not same new expression. new expression calls operator new obtain memory and then calls constructor requested on memory. operator new not throw other std::bad_alloc , later call constructor can throw whatever user code wants. compare new expression operator new .
