Chapter 11.3, Problem 43E

(a)

To determine

To calculate: The output value of A in the program for $\text{X}=0\text{,Y}=0$.

LET $\text{Z}=\text{X}+\text{Y}$

IF $(Z\ne 0)$ AND $\left(\text{X}>0\right)$

THEN LET $\text{A}=6$

ELSE LET $\text{A}=4$

(b)

To determine

To calculate: The output value of A in the program for $\text{X}=\text{8,Y}=-\text{8}$.

LET $\text{Z}=\text{X}+\text{Y}$

IF $(Z\ne 0)$ AND $\left(\text{X}>0\right)$

THEN LET $\text{A}=6$

ELSE LET $\text{A}=4$

(c)

To determine

To calculate: The output value of A in the program for $\text{X}=-\text{3,Y}=\text{3}$.

LET $\text{Z}=\text{X}+\text{Y}$

IF $(Z\ne 0)$ AND $\left(\text{X}>0\right)$

THEN LET $\text{A}=6$

ELSE LET $\text{A}=4$

(d)

To determine

To calculate: The output value of A in the program for $\text{X}=-\text{3,Y}=\text{8}$.

LET $\text{Z}=\text{X}+\text{Y}$

IF $(Z\ne 0)$ AND $\left(\text{X}>0\right)$

THEN LET $\text{A}=6$

ELSE LET $\text{A}=4$

(e)

To determine

To calculate: The output value of A in the program for $\text{X}=\text{8,Y}=-\text{3}$.

LET $\text{Z}=\text{X}+\text{Y}$

IF $(Z\ne 0)$ AND $\left(\text{X}>0\right)$

THEN LET $\text{A}=6$

ELSE LET $\text{A}=4$

(f)

To determine

To calculate: The output value of A in the program for $\text{X}=\text{3,Y}=-\text{8}$.

LET $\text{Z}=\text{X}+\text{Y}$

IF $(Z\ne 0)$ AND $\left(\text{X}>0\right)$

THEN LET $\text{A}=6$

ELSE LET $\text{A}=4$
