Question

I was trying this piece of code to check whether the divide by zero exception is being caught:

int main(int argc, char* argv[]) {     try     {       //Divide by zero         int k = 0;         int j = 8/k;     }     catch (...)     {         std::cout<<'Caught exception\n';     }     return 0; } 

When I complied this using VC6, the catch handler was executed and the output was ‘Caught exception’. However, when I compiled this using VS2008, the program crashed without executing the catch block. What could be the reason for the difference?

Answer 1

Enable structured exception handling under project -> properties -> configuration properties -> c/c++ -> code generation -> enable c++ exceptions.

Use a try except. Ideally with a filter that checks the exception code then returns the constant signalling if it would like to catch. I have skipped that out here but I recommend you see here for examples of the filter.

#include <iostream> #include <windows.h>  int main(int argc, char* argv[]) {     __try     {         //Divide by zero         int k = 0;         int j = 8/k;     }     __except(EXCEPTION_EXECUTE_HANDLER)     {         if(GetExceptionCode()==EXCEPTION_INT_DIVIDE_BY_ZERO)             std::cout << 'Caught int divison exception\n';         else             std::cout << 'Caught exception\n';          system('pause');     }     return 0; }
