Vi and vim Editor (12): advanced editing method (3) @ Function: The naming buffer provides another method to create a macro, that is, you can save a complex command sequence to a naming buffer, and then run the content in the buffer using the @ command. For example, enter the following line in the insert mode: Delete the row and save it to the "a" Naming buffer. Then, you can move the cursor to the header of a word and execute "@ ", you can execute the content in the buffer zone as a command. I

GraphicsEnvironment class saves the graphic objects and a set of colors, including the width and height. The saveAsPng method outputs the current image to a specified file. GraphicsObject is a required interface for any graphic object. To start using this interface, you must use the render method to draw this object. It is implemented by a Line class. it uses four coordinates: the x value of start and end, and the y value of start and end. It also has a color. When render is called, this objec

The "extern" keyword indicates that the Add method declared here is an external call.Once the method has been declared, it can be used just

method of passing the value calls the copy constructor of the class. Thus causing infinite recursion to invoke the copy constructor. Therefore, the parameters of the copy constructor must be a reference.What needs to be clarified is that the pass pointer is actually a value, and if the copy constructor above is written as Cclass (const cclass* c_class), it will not work. In fact, all other passes are values, except that the pass-through reference is not a passing value.Start with a small exampl
