Answer the following questions.
a. For what integer values of D will the code between if and end execute?
if D >= – 1 && 3 > D
code
end
b. For what values of F will the code between if and end execute?
if F >= 100 || F <= 5
code
end
c. What combinations of values for B and Q will cause a warning to be displayed?
if B >100 || (B<20 && Q~=0)
fprintf ('WARNING! Pararneters out of bounds. \n')
end
a.

Find the integer values for which the code inside the if and end executes.
Answer to Problem 1ICA
The integer values for which the code inside the if and end executes are
Explanation of Solution
The English translation of the if statement says that, the if statement is true when the variable D is greater than or equal to -3 and less than 1.
So from the number line, the values of D for which the expression is true are
Conclusion:
Hence, the integer values for which the code inside the if and end executes are
b.

Find the integer values for which the code inside the if and end executes.
Answer to Problem 1ICA
The integer values for which the code inside the if and end executes are
Explanation of Solution
The English translation of the if statement says that, the if statement is true when the variable F is greater than or equal to 100 or less than or equal to 5.
So from the number line, the values of F for which the expression is true are
That is F can be any real number excluding numbers between 5 to 100.
Conclusion:
Hence, the integer values for which the code inside the if and end executes are
c.

Find the integer values for which the code inside the “if” and “end” executes.
Answer to Problem 1ICA
The integer values for which the code inside the “if” and “end” executes are
Explanation of Solution
The English translation of the if statement says that, the if statement is true when the variable B is greater than 100 or when B is less than 20 and Q is not 0.
So from the number line, the values of B and Q for which the expression is true are
Conclusion:
Hence, the integer values for which the code inside the “if” and “end” executes are
