Is Zero an Octal Literal in C ?
In programming, integer literals represent numeric values in code. While zero (0) appears to be a standard numeric value, its interpretation in different number systems can vary.
Decimal vs. Octal Literals
Decimal literals are written without a prefix and represent base-10 numbers, while octal literals are written with a leading 0 (zero) and represent base-8 numbers.
Does C Treat 0 as an Octal Literal?
According to the C Standard (2.14.2), 0 is an octal literal. The syntax for integer literals in C is defined as follows:
octal-literal:
0
octal-literal octal-digit
This indicates that 0 itself is considered an octal literal.
Conclusion
Therefore, the answer to the question is yes, 0 is an octal literal in C . However, it's important to note that in modern C code, octal literals (including 0) are rarely used. This is primarily because using octal literals can lead to confusion and potential errors due to their non-intuitive representation of base-8 numbers.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
