I wouldn't say it is an antique. :)

This is C and it works, although the main arguments are not needed.

This is C++ code but it is WRONG. Although it compiles strangely in
Dev-C++ it is WRONG. You can't delete argv since it is a static object
on the stack and not on the free store. Also it should be char *argv[]
or char **argv.

Also after the official C++ standard he should have used the using
namespace std; or using std::cout directives.

The name is ANSI C99 and the answer is no. The code was a C++ attempt.

None. stdlib.h is not needed in that code.

The order of parameters doesn't matter.
