using namespace std;
class vec
{
public:
vec(float f1, float f2)
{
x = f1;
y = f2;
}
vec()
{
}
float x;
float y;
};
vec addvectors(vec v1, vec v2);
int main()
{
vec v1(3, 6);
vec v2(2, -2);
vec v3 = addvectors(v1, v2);
cout << v3.x << ", " << v3.y << endl;
}
vec addvectors(vec v1, vec v2)
{
vec result;
result.x = v1.x + v2.x;
result.y = v1.y + v2.y;
return result;
};
