question about c++ in xcode

[xxcysxx]

hello folks,

in visual studio i can just use

using namespace std;
int main()
{
return 0;
}

and in xcode i have to use

using namespace std;
int main(int argc, const char * argv[])
{

return 0;
}

for it to work? how come i cant do the main without any argument in the parenthesis like i did in visual studio?
i tried to do it and get compile failed.

i did use google to search but i only understand what the argument does, but i still don't understand why xcode requires it where as visual studio doesn't.

thanks for any inputs folks

What some compilers allow you to get away with is quite shocking!

I generally write my C code in gEdit and then compile it by using make in Terminal... I'm pretty sure it'll compile without any arguments in main() just fine.

? I never had to use them in Xcode. You *should* use them because its considered proper practice but most programming books omit them for some reason.

Most of the time when C++ code compiles on Windows and doesn't compile with either gcc or clang, it turns out that the code was illegal in the first place but some windows compiler still accepted it.
