Why would this work? - and it does! any thoughts?


#include<iostream>

using namespace std;


void init(char **str){ *str="Awesome"; }
main(){

char * str;

init(&str);
cout<<str<<endl;
}

Well, technically it shouldn't work because main() is not a valid prototype
for main. It should be 'int main()'. But that is beside the point here.

Other than that, what is the problem? It is equivalent to

int main()
{
char* str;

str = "Awesome";
cout << str << endl;
}

Why wouldn't it work?

I think it would help us reply constructively if you could explain what's so
weird, unexplained or anomalous about the pieces of code you're posting, so
that we could focus our comments accordingly. Is it the "main()" that you
find so weird? What sort of "thoughts" do you want?
