if can be chained along to check multiple conditions. The first condition which evaluates to true ends up being the one picked. If none of the conditions evaluate to true, then the code in the final otherwise is executed. For example, consider the following code:

if $(1>10)$ then:

x :$=0$

otherwise if $(10>2)$ then:

x :$=1$

otherwise:

x :$=2$

In this case, since $1>10$ evaluates to false, the first bit of code is skipped. The condition $10>2$ is then evaluated, producing true. Since this condition evaluates to true, the code underneath this specific condition is executed. This places value $1$ into variable x$.$ At this point, there is nothing left to exeucte.

Consider the following code:

if $(2>2)$ then:

x :$=0$

otherwise if $(2>4)$ then:

x :$=1$

otherwise if $(2>=5)$ then:

x :$=2$

otherwise:

x :$=3$

What value does program variable x hold when this code is finished executing?
