You can use exceptions like this:
void main(void)
{
try
{
blahblah=somecode();
if(!blahblah)
throw "something went wrong";
}
catch(char *error)
{
cout << error;
}
}
They're mainly used for error handling.. an easy way to jump out of a block of code. Note that you could have many other 'catch' blocks, that may take, say, an int, or any other datatype. try/catch blocks can be nested too, so you don't have to use them in main() only.
