Stored procedures offer many advantages over dynamic SQL, including improved performance and scalability. The SQL code in a stored procedure is parsed and normalized when you create it. Stored procedures

Dynamic allocation of an exception (as in this example) is not a good idea: class Err{public: Err(const char * description);};void f(){ if (disaster) throw new Err(“failed”); //exception object is dynamically

You can apply STL generic algorithms to a sequence of elements. They are defined in the header file . (on pre-standardized implementations, the name is used instead). Iterators are used

Even macros that look harmless can have detrimental effects. For example: #define twice(x) ((x)+(x)) The macro, twice, is well parenthesized and performs a simple addition operation. Despite its simplicity, there
