1.      Which two signs need to be interchanged to make the following equation correct?

5 X 4 + 12 -3  ÷ 6= 18

2. 2. Write the answers for the following

!true =  ?

true && false = ?

3.      Find the output

a.23>>3

b. 27<<2

c. 15&9

d. 15^9

e. 15 | 9

4. 4. ---, ----  Data types uses one address and two address to store a value

5. 5. x = 1, y = 2;

           z = x & y == 2;

                 z= ?

6. 6. Predict the output of the given pseudo code if the value of the number is 6: 

Read number

k = 2

i = 2

while i <= number:

                         k = k * i

                         i = i +1

end while

write k

• 1220

• 240

• 720

• 1440

7. 7.  What will happen for the below pseudocode:

   Set Integer res = 0 
            do 
                     --res 
                      display res 
                        res++ 
              While(res >= 0) 
               End do-while

• The loop will run a finite number of times.

• The program will terminate with an error.

• The program will enter an infinite loop, repeatedly displaying -1.

• The loop will run once and stop.

8. 8. Count the number of " * " printed by the given pseudo code when the input is 25. 

Write "Please enter a number" 
Read input 
Repeat while input > 0 
    if( input > 0 and input <=12 ) 
        Write  
    else if ( input >12 and input <=24 ) 
        Write * 
    else if ( input >24 and input< = 30 ) 
        Write *** 
    input -- 
    end if 
End while

9. 9. Count the number of " # " printed.

   For n = 0 to 14 do
                           display '#'
               if(m = 5) then do
                           break
                           End-if
                End-for

10. 10. What will be the output of the following pseudocode?

    For x = 0 to 8 do
                  For y = 0 to 6 do
                            display '#'
                End-for
                            If(x = 2) then do
                            break 
                            End-if 
    End-for
