Quiz question answers for chapter 8 are as follows:

The six relational operators are >, >=, <, <=, ==, and /=.
The three basic logical operators are .and., .or., and .not. where the leading and trailing periods are required.
The answers are .true., .true., .false., .true., .true., .false., and .false. where the leading and trailing periods are required.

The statements are as follows:

if (lives <= 0) then
    write (*,*) "Game Over"
end if

Note, this also could be done as follows:

if (lives <= 0) write (*,*) "Game Over"

The statements are as follows:

if (num < 0) then
    num = abs(num)
    write (*,*) "Variable num was made positive"
end if

The statements are as follows:

if (y /= 0) then
    z = x / y
else
    z = 0
    write (*,*) "Z not calculated"
end if

Note, another correct solution is as follows:

if (y == 0) then
    z = 0
    write (*,*) "Z not calculated"
else
    z = x / y
end if

The statements are as follows:

if (x <= 0.0) then
    f = x**2 * y
else
    f = x * y
end if
