new
why does c++ have its separate syntax for new & delete?
Why can't it just be regular function calls? New is essentially: malloc(sizeof(Foo)); Foo::Foo(); while delete is Foo:~Foo(); free(...); So why does new/delete end up having it's own syntax rather than being regular functions? ...

I've inherited a Visual Studio 6.0 project to convert to 2005. It includes this fantastic MyClass class below that client code uses everywhere by invoking placement new on an instance of it (greatly simplified here): #include <new> #include <cstdio> template<class T> class MyClass { public: // This is what the author assumed would...

My next thought was to use the & o...
