Analyze the following code fragments that assign a boolean value to the variable even.

Code $1$:

if $($number $2=0)$

even $=$ true;

else

even $=$ false;

Code $2$:

even number $2=0?$ true: false;

Code $3$:

even $=$ number $2=0$;

All three are correct, but Code $3$ is preferred.

All three are correct, but Code $2$ is preferred.

Code $3$ has a compile error, because you attempt to assign number to even.

Code $2$ has a compile error, because you cannot have true and false literals in the conditional expression.

All three are correct, but Code $1$ is preferred.
