QUESTION:

You want your program to execute statement 1 when A is false, B is false, and C is true, and to execute statement 2 otherwise. You wrote if not(A and B) and C then statement 1 else statement 2 end if Does this do what you want?

ANSWER:

Step 1 of 2

Consider the program given,

if not( and ) and  then

statement 1

else

statement 2

end if

The condition in the if statement is “not( and ) and ”. the condition “not( and )” will be true when “ and ” is false. The condition “ and ” is false when both  and  are false; also, either  or  is false, which should not be considered in this case. That means the condition will be true in the case that “either  or  is false”. That is not needed.

 So the condition written in the given code is wrong.
