This article describes a problem with the default handling of exceptions in Microsoft’s Visual C++ compilers. The problem is caused by the compiler’s extension to the C++ exception handling mechanism. I then give a technique that properly exploits this extension, bringing it into line with normal C++ exception handling. This allows programs to deal with [...]

Whenever you have a choice, you should use the C++ prefix increment and decrement operators (e.g. ++i) instead of the postfix versions (e.g. i++).

C++ specifies how compilers should deal with programs that misbehave. This article describes one of the effects of these rules: compilers may generate no code for the body of a misbehaved function, whether or not the function is ever called.
Consider this function
void furphy()
{
std:::cerr << “furphy”;
int* p = [...]
