C + + Exception learning

The code is as follows:

#include <iostream>

Class Texception

{

Public

Texception ()

{

Std::cout << "hello,world!" << Std::endl;

}

};

Double Func (double x, double y)

{

if (0 = = y)

{

throw new Texception ();

}

}

int Wrapfunc ()

{

Func (0, 0);

return 0;

}

int main ()

{

Try

{

Wrapfunc ();

}

catch (texception* e)

{

Std::cout << "Catch exception" << Std::endl;

}

catch (...) Catch all the exceptions

{

Std::cout << "Catch all Exception" << Std::endl;

}

return 0;

}

Analysis

When the throw new Texception,catch statement must be defined as a pointer, when the texception () object is thrown, the catch statement must be the object can be a catch (texception& e) or catch (const texception& e)
