int main()
{
unsigned a = 10;
int b = -15;
cout<<a+b;
return 0;
}
Is giving the output 4294967291. Can't figure out why?

Without knowing more, I would guess that the expression `a+b` is being treated as `unsigned`. But I do not know a parsing rule that would explain why. – vacuumhead Jan 21 '16 at 14:59

Try casting: `cout << "result: " << (int)a + b << endl;` – RHertel Jan 21 '16 at 15:06
