Here's the Solution to this Question

Let us state the value of $x$ after the statement

$``$ if $P(x)$ then $x:=1"$ ,

where $P(x)=``x>1",$ in the following cases:

a) If $x=0,$ the statemet $P(x),$ that is $``0>1"$ is false, and hence after the command $``$ if $P(x)$ then $x:=1"$ the value of $x$ is equal to 0.

b) If $x=1,$ the statemet $P(x),$ that is $``1>1"$ is false, and hence after the command $``$ if $P(x)$ then $x:=1"$ the value of $x$ is equal to 1.

c) If $x=2,$ the statemet $P(x),$ that is $``2>1"$ is true, and hence after the command $``$ if $P(x)$ then $x:=1"$ the value of $x$ is equal to 1.
