C++ implementation to add desktop right click new menu

It is not uncommon for programmers to create a new cpp file.
For convenience, we're used to right-clicking on a new file on the desktop instead of creating a new text document and then changing the suffix.
Baidu Google query 1, finally know how to add the registry.
Itchy hands, took time to write a procedure with cpp, convenient for later operation.
Customer demand is never able to meet, after the students test, wrote three versions in succession.
Next directly paste code ~
The first version can only add c, cpp and java suffixes.
