max:

5

• int max = 5

  print max:

  print 5

• int max = 5

  print “max:”

  print max

• int max = 5

  print “max:” //AppendLineFeed

  print max

• int max = 5

Consider the following code segment.

print ( “apple” )         //line break appended
print ( “banana” )    
print ( “pear  ” )    

What is printed as a result of executing the code segment?

• 1. apple
     bananapear

• 1. applebanana
     pear
     

• 1. apple
     banana pear

• 1. apple banana
     pear

Consider the following code segment:

double rate 2.25

/* missing code  */

  Which of the following could replace  /* missing code  */  so the output is 5.0 ?

• print (2 * rate + 0.5)

• 2. print (2 * (rate + 0.5))

• 3. print (2 + rate * 0.5)

• 4. It is not possible to replace the code and get an output of 5.0.

What is output when the following code segment is run?

int rate -4

int irate 2

int sum rate * irate

int irate irate + 3

print (sum * 2) 

• sum*2

• -16

• -22

• 22

Answer explanation

Solution:  sum get the value of rate * irate at the point it is assigned.  It does not change when irate gets modified

.  Which of the following statements would print  42 when executed?  Select all that apply.

• 1. print ( 42 * 1.0)

• 1. print (“42 * 2 / 2”)

• 1. print (42)

• print (“42”)

Answer explanation

 a would print 42.0, b would print, as a text string, 42 * 2 / 2

c would print 42 (the integer) and d would print 42 (as a text string)
