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#
, C++ is my bread and butter language. This is a specific type of cast called a C-Style cast. What it does in this case is transform the return type of the function to an int. In addition to this, C++ has several variants. The most used is static_cast.
