Mechanical mouse has a ball that turns rollers inside. If friction is lost between the ball and the mousing surface, or between the ball and the rollers, the mouse fails to work. In order to assure good contact with the mousing surface, the ball must be fairly heavy. When you change directions with the mouse, you must make the ball change rolling directions--an action that inertia likes to prevent.
An optical mouse makes use of an LED and some optics to detect surface texture and the changes in it as the mouse is moved. There are no moving parts
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 &.
<span>A return statement causes a value to be sent from a called method back to the calling method.
</span>When used in computer programming the return statement causes execution to leave the current subroutine and resume at the return address, where the term return address denotes the point <span>in the code immediately after where the subroutine was called.</span>
