Error: Id returned 1 exit status (undefined reference to 'main')
As we know that,
- Each program must have a main() function, compiler starts execution from the main() function - main() is an entry point to the program,
- And, the second this "C language is a case-sensitive language - uppercase words, and lowercase words are different".
This error is occurred on following cases,
- If main() is not written in lowercase, like you used Main(), MAIN(), mAin() or anything else.
- If main() does not exist in the program or by mistake you mistyped the main().
