What does g(-2, 5) evaluate to?

Question

What does g(-2, 5) evaluate to?

int g (int x, int y) {

x= x + y;

int z = 2 * x + y;

return z;

}

Answer 1

The function should return 11. The first operation

x = x+y changes the value of x to 3. The next operation does not specify any precedence. So C++ precedence rules take effect. * has greater precedence than +. So the operation is equivalent to z = (2 * x) + y = (2 * 3) + 5 = 11
