C problem

Question

In c language, if we declare and initialise main as a variable, shouldn't it produce a compile time error?
int main=3;
(It will print 3 ) why?
Can anyone explain?

Answer 1

But main is inbuilt function, i thought we can't use it as a variable name🤔

Answer 2

`main()` is not a inbuilt function. It's a user defined function.

No. `main` is not a keyword. It's a valid identifier. Declarating a variable `main` at function scope or block scope won't generate error.

If you declare `main` variable at file scope it'll generate error.

Answer 3

Main() is not a user defined function, its a predefined function
