Editor to share with you how to write the hexadecimal regular matching in the programming language. I hope you will get something after reading this article. Let's discuss it together.

It is composed of 0-9 Magi Amurf. The corresponding relationship between 0-9 and base 10 is: 0-9 corresponds to 0-9. The number of base 10-15 corresponding to N can be represented by the number of 0 Murray-(Nmuri 1) that exceeds 9 with the letter Amurf.

That is, it is composed of the character: 012345679ABCDEF

Hexadecimal numbers in C must start with 0x. For example, 0x1 represents a hexadecimal number. And 1 represents a decimal system. In addition, such as: 0xffPerson0xFFJOX102A, and so on. The x is also case-insensitive. (note: the 0 in 0x is the number 0, not the letter O)

So the regular match for programming languages such as C or C++ is:

\ b0 [xX] [0-9a-fA-F] +\ b

He can play Standard PvP match.

0xDEADBEEF 0xdeadbeef 0XDEADBEEF 0Xdeadbeef 0x12345678

Can't match.
