Draw a circle with the center (CX, CY) and write a number centered on it:
In general, in drawtext (text, CX, XY, paint), the vertex (CX, CY) is the starting point of the text, as follows:
Even if you use paint. settextalign (paint. Align. Center), the text is horizontally centered, but the vertical text is not centered. If you can get the text height, and then shift down to half, you can center:

Cy is almost her birthday. To avoid being tired of temporary overtime, I asked her to come out for dinner early. We had thai food last year. This year we chose a pizza store that is not Pizza Hut. The food tastes good, and the restaurant environment is also suitable for chatting. In short, I am very satisfied. I don't know if she is satisfied or not?
I noticed that she was dressed up today, with a thin fur coat lined with a pleated skirt, and then

prevent the Destructor from traversing the object. If the destructor of this object will be called, we must not clear the stack.Generally, the member variables of a class can be destroyed by the class's own destructor. Therefore, you should never push the member variables into the cleanup stack to avoid secondary deletion!
Two-Phase StructureStack cleanup is used to save the pointer to the heap-based object so that cleanup can be performed when an exception exits. This means that you must have
