All it'd take is a single drill hole and re-wiring the sensor, but it near the top of the window and no one's even gonna notice it's there. Like mneary said if you have eaves it's even more perfect you can recess it up, completely out of site.
Where C# is just different from C++. value types and reference types exist (struct is value-type, class is reference-type) value types live on the stack, reference types on the heap; references can point to null (must not be valid) code is packaged in assemblies in C#; no automatic conversion from int to bool in C#; main-function is called Main in C#
The two constructs are identical in C++ except that in structs the default accessibility is public, whereas in classes the default is private.opy. Classes and structs are the constructs whereby you define your own types. Classes and structs can both contain data members and member functions, which enable you to describe the type's state and behavior.
