ASCII code comparison table

ASCII code is "American Standard Code for Information Interchange", American Standard Code for Information Interchange: 1, 0, NUL; 2, 1, SOH; 3, 2, STX; 4, 3, ETX, etc., ASCII code includes many other characters and symbols. Each character corresponds to a unique integer value, and these integer values ​​are called ASCII codes.

This is just the ASCII code Part of the lookup table, ASCII includes many other characters and symbols. Each character corresponds to a unique integer value (0-127), and these integer values ​​are called ASCII codes. ASCII codes are used to transfer text information between computers and communications devices, and are used extensively in computer programming and data processing. A complete ASCII code table can be found on the Internet.
