The Silent Rule : In C (and Java/Python/JS), if you put a Zero (0) at the start of a number, the compiler treats it as Octal (Base 8). It is not a normal Decimal number anymore. ​2. The Math : ​Decimal 20 = 2 \times 10 + 0 = 20 ​Octal 020 = 2 \times 8^1 + 0 \times 8^0 ​2 \times 8 = 16. ​3. The Lesson : Never start a number with 0 unless you mean to convert bases. ​int x = 20; -> 20 ​int x = 020; -> 16 ​One zero chan

When you write return 0;, you’re basically saying — 👉 “The program ran successfully, without any errors.” If something goes wrong, the program can return 1; or any non-zero value to indicate an error or abnormal termination. 💻 Example Code: #includ
