Question

1) True|False: You are about to write your pseudocode for the program that will read many time cards (with time in & out hours), and output the total regular hours and total overtime hours. The first step of your pseudocode can be    “ Set Total_regular_hours to zero”.    

2)True|False: You are about to write your pseudocode for the program that will read many time cards (with time in & out hours), and output the total regular hours and total overtime hours. The last step of your pseudocode can be    “ Output Total_regular_hours and Total_overtime_hours”.

3)

True|False: You are about to write your pseudocode for the program that will read many time cards (with time in & out hours), and output the total regular hours and total overtime hours. The following pseudocode is complete and correct.     

1. Set Total_regular_hours to zero;
2. Set Total_overtime_hours to zero;
3. Get client’s Time_in and Time_out;
4. Let Regular_hours be (Time_out – Time_in);
5. If Regular_hours is more than 8 hours

      then   Overtime_hours is (Regular_hours – 8)

and   

                 Regular_hours is only 8 ;

       else Overtime_hours is zero;

6. Add Overtime_hours to Total_overtime_hours;
7. Add Regular_hours to Total_regular_hours;
8. If there is more time cards to read, then go to step 3;
9. Output Total_regular_hours and Total_overtime_hours;

4)True|False

You are about to write pseudocode to compute the result value of the formula:  

( X * Y / Z + P + R )  

The following pseudocode is complete and correct.

1. Compute X * Y, and put its result to T1 ;
2. Compute Z + P, and put its result to T2 ;
3. Compute T1 / T2 , and put its result to T3 ;
4. Compute T3 + R, and put its result to T4 ;
5. The final result value is in T4 ;

Answer 1

1)pseudocode can be    “ Set Total_regular_hours to zero”.  

Ans: True

because starting of the program regular_hours is zero and when ever we take user choice hours are more than 8 or exactly 8.

2) pseudocode can be    “ Output Total_regular_hours and Total_overtime_hours”.

Ans:True

we are calculating the Total_regular hours and total_overtime_hours.so we print output of this two values.

3) Ans : True

what ever mentioned in the third question is correct because (if regular hours are more than 8 then overtime is regular hours-8) and if regular hours is exactly 8 hours then the client don't to ant extra time.so in this case overtime is zero.all statements are correct.

4) Ans :False

Compute Z + P, and put its result to T2 ; is not correct because according to pemdas rule in programming * and / are having equal priority but left to right associative property followed. According to that first

1. Compute X * Y, and put its result to T1 .
2. Compute T1/Z and put its result to T2 ;
3. Compute T2+ P, and put its result to T3 ;
4. Compute T3+ R, and put its result to T4 ;
