#include <vector>
;
int main()
{;
	{;
		;{;std::vector<int>{-1, {}, 1};};
	};
};
;

I showed this to ResidentBiscuit and all he had to say was "what the hell lol".

how did you come up with this?

[N36fSL3A]

	{;
		;{;std::vector<int>{-1, {}, 1};};
	};

How is that even valid? VS2012 complains whenever I do this:

{/*code here*/};

i kind of get it looking closely. the semicolons and the bracket scoping was throwing me off. really it would just be this:

#include <vector>

int main()
{
     std::vector<int>{-1, {}, 1};
}

im still not quite sure what that does though

@DTSCode^2: Dyrand and I were in IRC with ResidentBiscuit and we got on the topic somehow.

@Lumpkin: Try { /*code here*/; } instead.

@DTSCode^1: Yes, that's right - it just makes a temporary vector of ints that contains -1, 0, and 1.

is there another channel beyond #cplusplus? cause i dont think you got on that today. i didnt see it in the logs. also, when would you need to create a temporary vector of ints like that?

We have an IRC channel for ChessPlusPlus, sometimes we get off topic.

In this case it's pointless, but as an example of when you would want to create a temporary instance of anything is to pass it to a function or constructor.

My brain just fractured trying to work out what the point of that code was. Thank you for explaining a bit, otherwise I might have started drooling and talking to myself.

[long double main]

Wait, is this supposed to look like something, or is it just a random piece of code with a bunch of curly braces and semicolons?

...I guess with a little stretch of the imagination, you can kinda make yourself think that it looks like a sideways image of a rocket leaving a launch pad....

Anyways, this is my favorite random piece of code (I don't even know why):

int main()
{
    [](){}();
}

@LDM: Even better:

int main()
{
    []{}();
}
