The following pages contain summaries of two character sets commonly used on PC-compatible machines. The first is for the IBM-850 character set, commonly available on Linux terminal utilities such as Konsole and GNOME Terminal. The second is the older “Code Page 437” set, which is basically the character set coded into the BIOS ROM of IBM-compatible PCs.
There is one glyph block for each character in each set. Each glyph block includes the following information:
The three-digit decimal form of the character number, from 000–255. These are in the upper-right corner of each block.
The hexadecimal form of the character number, from 00–FF. These are in the lower-left corner of each block.
The character glyph is in the center of the block.
For control characters from 0–31, the name of the control character (e.g., NAK, DLE, CR, etc.) is printed vertically in the lower-right corner of the block.
Note that the IBM-850 character set is not loaded by default in common Linux terminal utilities and must be specifically selected from the options or settings menu before the character set will be displayed in the terminal window. For more on this, see Chapter 6.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
