ROSIVID/DNEDIVID = TLUSER ESLE 83+E! = TLUSER NEHT .0 = ROSIVID FI

Would yeld a different result but you haven't successfully divided by zero
since the logic of your code avoids the divide completely if the DIVISOR
is zero.

There is a trick you can use in C++ to do it. C++ allows all operators to
be overloaded. Thus in C++ you can make up you own rules about ADD,
SUBTRACT, MULTIPLY and DIVIDE to that 1/0 is perfectly legal.

In C++ you can make the main part of your program:

int main(void){ return 1/0; }
