Answer:

False.

Explanation:

When we declare a variable as reference type we have to initialize that variable otherwise the compiler will give error that the reference variable is not initialized.You also cannot initialize the variable Foo& with NULL value because it is a reference variable and we have to initialize it.

On the other there is no need to initialize the variable Foo * since it is a pointer it can also store NULL value.

So the answer is only Foo* can store NULL value not Foo &.

DedPeter [7]

Answer:

B. 80%

Explanation:

To assertain:

1 hit takes 1 clock cycle while 1 miss takes 6 clock cycles

Assuming that:

  1. we have 100 accesses in total,
  2. p are hits,
  3. 100 - p are misses

So, p + (100 - p)*6 = 200\\ \\p+600-6p = 200\\\\-5p + 600 = 200\\\\5p = 600 -200\\\\p = \frac{400}{5} \\\\p= 80

Hence, option B. 80% will result in an effective access time of 2 clock cycles.
