d1 is passed as reference, So changing value with in the function reflects in main. d2 is passed as value, so changing value with in the function does not reflects in main. In foo function: ---------------- c is referencing a. and changing the value of a using reference c with the line "*c = LEFT". Then reassigning c with b. But changing the value of b does not reflects in main. So, after the function call value of a is LEFT and value of b is DOWN. So, Output is d1 = 0, d2 = 1 d1 = 2, d2 = 1 Note: enums starts with 0.
