Exception Handling

Just like Java, C++ has a try-catch-throw mechanism for handling exceptions.

class Exception { };

void f( ) {

Exception e;

throw(e);

}

void main( ) {

try {

f ( );

}

catch(Exception error) {

cerr << “Found an exception” << endl;

}

return 0;

}

The g++ compiler requires that any C++ code containing the try-catch-throw keywords be compiled using the -fhandle-exceptions switch

The try block: encapsulates any code that can throw an exception

The catch block: catches the exception thrown and deals with it or throws it again

We can also throw and catch basic types such as int, double, etc. in addition to first-class objects
