Question

1. Is the function void or return

a. void
b. return
2. What is the result of the following expression: int r = 3; r%2 == 0;
a. it evaluates as true
b. it evaluates as false
c. nothing happens

Answer 1

(a) void

(b) Nothing happens

Step-by-step explanation:

Solving (a): void and return

A function that returns no value is referred to as a void function.

On the other hand, a void can not be return or named return.

So, the function is void

Solving (b):

r = 3

Required

The result of r%2 == 0

Substitute 3 for r in r%2 == 0

3%2 == 0

3%2 is 1.

So, we have:

1 == 0

Hence, the equivalent of r%2 == 0 is 1 == 0.

However, nothing will happen because there is no instruction attached to the statement (i.e. r%2 == 0;)
