Today, I will talk to you about the conversion between hexadecimal and RGB color values and how to judge a prime number and inline function and object-oriented. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents. I hope you can get something from this article.

Conversion between hexadecimal and RGB color values
