C++ struct help :(

[TAKTAK]

I needs c++ help
I need to return 3 values (1 int, 2 strings) from a function, one of which is being returned direct by the return function (the int). So i'm employing a struct for the final 2.
I can pull the values from the struct back within the same function, but I can't pull them back in other functions, it just returns blank.

I have a struct in a header file, populated by one function via an object i.e.

int function1()
{
structname structObj
structObj.firstval = value
structObj.secondval = value2
}

int function2()
{
structname structObj
cout << structObj.firstval
cout << structObj.secondval
}

How do I pull the values out in function 2?
Pointers? How do I set the pointers up correctly for a struct? I'm guessing it's something easy that i'm missing but I just can't see the wood for the trees right now

Just return the struct like any other value:

struct sStruct {
	int id;
	string str1;
	string str2;
};

sStruct setStruct(int id, string str1, string str2) {
	sStruct setStruct;
	setStruct.id = id;
	setStruct.str1 = str1;
	setStruct.str2 = str2;

	return setStruct; 
}

void printStruct(sStruct printStruct) {
	cout << printStruct.str1 << printStruct.str2 << endl;
}

int main() {
	sStruct mainStruct;

	mainStruct = setStruct(1, "string 1", "string 2");
	printStruct(mainStruct);

	return 0;
}

Tested, it works.

Aaaaaaah, I see

Thankyou very much, in the end I moved my filename grabbing to the next function, which does some work on the binary files, before I saw your reply

I'm confused.

You've got a local struct in two methods, so its garenteed to be different as its stack alocated.

You then want to get the result from the first functions changes?

surely you then want to reutrn the struct in the first func, rather than int?

edit: lolwut a 12 hour delay in chrome posting this?

Yeah I was being an eedjit expecting the struct to magically contain the values even though I never actually passed them accross, I only ever populated it for that specific function. Aaah well, too much coursework at once to fix it. It does what the brief asks for so I guess it's okay..
I guess it's something I can mention in the exam in an hour..
