1. Given this function definition int foo(int& x, int y) { int z = x + y; x = 0; y = 0; return z; } which of the following is NOT true?

   		the return value of foo depends on the original values of x and y.
   		if we removed the assignments to x and y, the return value of foo would not be changed, only a side effect.
   		the variable passed as x will always be 0 after foo returns.
   		the variable passed as y will always be 0 after foo returns.
