Ah yes, I completely forgot about MSVC...

The reason I asked this question is because I was reading the C standard and
found the following parts at 5.1.2.2.1 [1] and at 6.7.5.3/14 [2]:

    The function called at program startup is named main. The implementation 
    declares no prototype for this function. It shall be defined with a return 
    type of int and with no parameters:

        int main(void) { /* ... */ }

    or with two parameters (referred to here as argc and argv, though any names 
    may be used, as they are local to the function in which they are declared):

        int main(int argc, char *argv[]) { /* ... */ }

    or equivalent; 9) or in some other implementation-defined manner.

and

    An identifier list declares only the identifiers of the parameters of 
    the function. An empty list in a function declarator that is part of 
    a definition of that function specifies that the function has no 
parameters. 
    The empty list in a function declarator that is not part of a definition of 
    that function specifies that no information about the number or types of 
    the parameters is supplied.


In other words, all the tests that use `int main()` are open to accept 
any number of parameters, correct?

Was this implemented intentionally or just happened?

Please advice.

Thank you very much.
