Octal to Text Principle
Octal → decimal (each byte)
141 (oct) = 1×64 + 4×8 + 1 = 97 (dec)
97 = ASCII 'a'
Each octal number converts to decimal 0-255, maps directly to ASCII character.
⚠
Octal digits 0-7, each byte 000-377, whitespace optional.
What Is Octal-to-Text?
Convert octal (base-8) numbers to plain text ASCII. Each byte octal → decimal 0-255 → ASCII character.
Base-8
Digits 0-7, each digit = 3 bits.
Byte Mapping
000-377 octal = 0-255 decimal.
ASCII
0-127 standard ASCII, 128-255 extended.
Whitespace
Spaces/newlines allowed between octal bytes.
💡 Teaching Example: Convert 141 145 154. 141=97='a', 145=101='e', 154=108='l' → 'ael'.
