Unable to pass struct variable to class function

[togar4071]

Stumped. Trying to pass a struct variable to class member function. Get syntax error as the struct variable is not being passed to the class function.

#include <iostream>
using namespace std;

class Example
{
public:
	void foo(St1 var)
	{

	}
};

struct St1
{
	int x, y;
};


int main()
{
	Example e1;
	St1 s1;
	s1.x = 3; s1.y = 6;

	e1.foo(s1);

	return 0;
}

// Errors given:
// Syntax error:  identifier 'St1'
// 'Example::foo': function does not take 1 argument

Define your struct BEFORE your class definition.

And PLEASE, learn to use code tags, it makes reading your source much easier.

You can edit your post and add code tags.
