ASCII Value

#java #javascript #programming #ascii

Computers only understand numbers. So how do they handle letters, punctuation, and symbols? ASCII — the American Standard Code for Information Interchange, published in 1963.
Every character you type is secretly a number. Press A and your computer stores 65. Type a space and it stores 32. ASCII defines 128 such mappings — from 0 to 127 — covering everything a classic keyboard can produce.

The four regions of ASCII

              Control characters
              0 – 31
              Non-printing signals: newline, tab, backspace, null
Enter fullscreen mode Exit fullscreen mode 
              Digits & punctuation
              32 – 64
              Space, !, ", 0–9, :, ;, @, and more
Enter fullscreen mode Exit fullscreen mode 
             Uppercase letters
             65 – 90
             A through Z
Enter fullscreen mode Exit fullscreen mode 
            Lowercase letters
            97 – 122
            a through z
Enter fullscreen mode Exit fullscreen mode
