why was exception not handle?

#include class ccc { public: ccc(int i) { m_i = i; } int m_i; }; void f(bool b) throw( ccc ) { if(b) { throw new ccc(5); } } main() { try { f(1); } catch (ccc) { std::cout<<"catch call"; abort(); } } the catch not run;

Because your not catching what you throw:

throw new ccc(5); // Here you throw a ccc*
 
catch (ccc) // But here you catch a ccc

To fix:

// Throw like this:
throw ccc(5);
 
// Or catch like this:
catch (ccc* pC)
{
     delete pC;
     std::cout<<"catch call";
     abort();
}
